- a disk cartridge 10 according to the present embodiment comprises a cartridge body 13 by combining an upper half 11 and a lower half 12 made of a synthetic resin material.
- a magneto-optical disk (hereinafter, referred to as a disk) 14 is rotatably housed in 3 as a recording medium.
- the cartridge body 13 is provided with an openable shirt 15. When not in use, the shirt 15 closes the opening of the cartridge body 13 to prevent foreign matter from adhering to the disc 14. Have been.
- the shirt 15 When the disc cartridge 10 is loaded into the recording / reproducing apparatus, the shirt 15 is opened and the pair of reference pins 17 and 17 of the reference base 16 on the recording / reproducing apparatus side is connected to the lower half 12.
- a reference hole (not shown) is engaged, the lower surface of the lower half 12 is received by the pair of receiving portions 18, 18 of the reference base 16, and the disk cartridge 10 is horizontally supported. Also, the outer edge of the upper surface of the upper half 11 is brought into contact with a pair of holding springs 19, 19, so that the disc cartridge 10 is held.
- the disk 14 is chucked to a disk table (not shown) and is driven to rotate by a spindle motor. Then, the recording Z reproduction operation is performed by the optical head ⁇ the magnetic head which faces the disk 14 through the opened opening of the shirt 15.
- a print layer 20 is provided on the outer edge and substantially the center of the main surface 13 a (the upper surface of the upper half 11) of the cartridge body 13.
- the printing layer 20 is mainly composed of a medium constituting the ink 23 as shown in FIG. 2, a writing filler 21 contained in the ink 23 and capable of writing, and contained in the ink 23. And resin particles 22 having an average particle diameter equal to or greater than the average particle diameter of the writing filler 21.
- the medium for example, a binder containing biel chloride-acrylic resin or the like as a binder and containing a diluting solvent or an auxiliary agent is used.
- porous (porous) particles such as calcium carbonate and silica
- cowhide is used to further increase the water absorption effect. May be contained in finely powdered protein powder.
- the resin particles 22 have a flexural modulus of not less than 98 MPa and not more than 980 MPa (10000 to: LOOOO kgi / cm 2 ), and have an average particle diameter of
- a polyurethane resin of 10 m is used. Since the average particle diameter of the above-mentioned writing filler 21 is 10 m or less, resin particles 22 having an average particle diameter larger than this are used.
- the optimum particle size of the resin particles 22 is 5 zm or more and 20 m or less. If the particle diameter of the resin particles 22 is smaller than 5 / m, the resin particles 22 will be buried between the writing fillers 21 and a sufficient effect cannot be obtained. If the particle size of the resin particles 22 is larger than 20 m, the resin particles 22 cannot pass through the screen mesh, and the height difference between the resin filler 21 and the writing filler 21 increases, so that the writability increases. Will decrease.
- a silk screen method using a stencil of about 180 to 250 mesh (mesh is the size of a mesh per inch) is most suitable.
- the thickness of the formed ink 23 is about 5 m to 10 m.
- the content ratio of the resin particles 22 is optimally not less than 3 parts by weight and not more than 10 parts by weight. If the resin particles 22 are less than 2 parts by weight, the amount of the resin particles is too small to sufficiently receive the vibration of the welding horn.
- the upper limit of the content ratio of resin particles 22 is 10 parts by weight. In order to obtain desired writing characteristics in the printing layer 20, it is necessary to add about 20 parts by weight of the writing filler 21. However, it is desirable that the total amount of the filler (components other than the medium and the solvent) does not exceed 30 parts by weight, and if it does, the durability of the ink will be extremely reduced, and the base material (upper half) Adhesion failure with 1 1) occurs. Therefore, it is not desirable that the upper limit of the content ratio of the resin particles 22 exceeds 10 parts by weight.
- the printing layer 20 is configured not only as a printing layer for writing but also as a vibration absorbing layer for suppressing vibration of the cartridge body 13 in the recording / reproducing apparatus.
- vibrations caused by a high-speed rotation of a spindle motor on the recording / reproducing apparatus and the like are caused by reference pins 17 and 17 of the base 16 and receiving sections 18 and 18 From the cartridge body 13.
- vibration is transmitted from the holding panels 19, 19 to the cartridge body 13.
- the vibration of the cartridge body 13 also affects the rotating disk 14 to a considerable extent, causing the disk 14 to oscillate. Therefore, when the disk 14 vibrates, the signal read by the optical head also changes, which also affects the reproduction waveform of a music signal or the like, and as a result, there is a problem that faithful reproduction is not performed. I do.
- the resin particles 22 constituting the printing layer 20 have an average particle diameter of 10 m and a flexural modulus of 98 to 98 MPa, which is relatively soft, so that the vibration absorbing effect is reduced. And the vibration of the cartridge body 13 can be attenuated. That is, when the vibration is transmitted to the printing layer 20, the resin particles 22 vibrate, and the vibration energy is converted into heat energy, and the vibration is attenuated.
- the upper surface (main surface 13 a) of the upper half 11 is supersonic.
- the resin particles 22 having a large average particle diameter in the printed layer 20 are welded to the welding horn 9. Therefore, the writing filler 21 is prevented from directly contacting the welding horn 9. Therefore, when the resin particles 22 receive the ultrasonic vibration from the welding horn 9, the writing filler 21 is prevented from dropping or deforming from the ink 23. As a result, the appearance quality of the printing layer 20 and thus the disc cartridge 10 is prevented from being degraded.
- the printing layer 20 is also used as a vibration absorbing layer, the vibration of the force cartridge body 13 in the recording / reproducing apparatus is reduced, and a faithful reproducing operation is performed. Obtainable.
- Protein powder 8 parts by weight
- Resin particles 4 parts by weight
- resin particles 22 were made of polyurethane particles A with a flexural modulus of 68.6 MPa, polyurethane particles A with a flexural modulus of 98 MPa, polyurethane particles B with a flexural modulus of 98 MPa, and polyurethane particles C with a flexural modulus of 980 MPa.
- Ultrasonic waves were used for each of the particles with elasticity of 6 86 MPa, acrylic particles A with a flexural modulus of 13 72 MPa, and acrylic particles B with a flexural modulus of 31 36 MPa.
- the number of samples in which the surface of the printed layer 20 was scratched to the extent that the appearance was poor at the time of welding was examined.
- the average particle diameter of the resin particles 22 was 10 im for all particles.
- the average particle diameter of the writing filler (calcium carbonate, silica, protein powder) is 10 m or less. Table 1 shows the experimental results. The number of trials was set to 10 (volume).
- the conditions for ultrasonic welding were the same as before: the pressing force was 196 kPa, the frequency was 20 kHz (longitudinal vibration), the application time was 0.28 seconds, and after the ultrasonic vibration was stopped. Has a retention time of about 0.1 second.
- the broken line shows the vibration characteristics of a conventional disk cartridge (in this example, only the ink layer containing no resin particles and no writing filler).
- polyurethane particles C shown in Table 1 were used as the resin particles 22.
- the printing portion was the outer edge of the force cartridge body 13 and the approximate center of the main surface 13a, and the same applies to the conventional disk cartridge.
- the cartridge according to the present invention has reduced vibration compared to the conventional force cartridge.
- the peak power at 150 Hz is greatly reduced (-11.0.l dB) compared to the conventional (-10.9 dB).
- the printing layer 20 is formed on the outer edge and the substantially central portion of the main surface 13 a of the cartridge body 13.
- the present invention is not limited to this.
- the print layer 20 may be formed over the entire area of the main surface 13a.
- the solvent type ink is used, but an ultraviolet curable resin may be used as the medium.
- the mixing ratio of the various components is the same as in the case of the solvent type ink.
- the present invention is applicable not only to disk (FD) and cartridge type optical disks or magneto-optical disks, but also to tape-shaped recording medium cartridges (cassettes).
- the printing layer for writing formed on the main surface is not rubbed and scratched, and it is possible to prevent the deterioration of the appearance quality. it can.
- the printing layer can be effectively used not only as a writing layer but also as a vibration absorbing layer of the cartridge body, and a faithful recording / reproducing function can be ensured.
