Abstract

　　ホスト（１００）からのリードコマンドに応じて、リード処理し、且つライトコマンドに応じて、ライト処理する媒体記憶装置において、受領したリードコマンドにより、ホスト（１００）が、連続データの再生処理のため、一定間隔で発行されるリードコマンドであることを認識し、再生処理中に受信したライトコマンドに対し、ライト処理で、前記ライト失敗の可能性があるかを判定し、ライト失敗の可能性がある場合に、一定間隔で発行されるリードコマンドの受信を許可する制御回路（２８）を設けた。音楽や映像の再生処理中に、リードコマンドの間に送信されるライトコマンドの処理遅延により、リードコマンドの受け付け及び処理が遅延することを防止でき、音楽や映像再生の途切れを防止できる。
