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、受領したリードコマンドにより、ホストが、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のライト処理で、ライトリトライが発生した場合に、そのライト処理を中断し、データバッファ(38)にリードデータの格納域をアロケーションして、リード処理を実行して、ライト処理を再開する制御回路(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。
