Abstract
There is disclosed, an analog/digital compatible reproducing system, particularly a stationary head system using a digital recorded magnetic tape having a plurality of, n, digital data recorded tracks, and an analog recorded magnetic tape having a first analog recorded track and a second analog recorded track between which a guardband of a certain width is provided, so as to reproduce signals from the digital recorded magnetic tape by driving n reproduce magnetic head elements respectively corresponding to the n digital data recorded tracks, and to reproduce the analog recorded magnetic tape by driving a plurality of, m, reproduce magnetic head elements of said n reproduce magnetic head elements, corresponding to the first and second recorded tracks so that common outputs can be produced from the m reproduce magnetic head elements. There is also disclosed a tape cassette used in such system.
