SECTOR DATA TRANSFER DEVICE AND SECTOR DATA TRANSFER METHOD

摘要

PROBLEM TO BE SOLVED: To improve the retrieval capability of target sector data by outputting the sector data at the time of detecting an initial sync-pattern before synchronism is established. ;SOLUTION: This device has a sync-pattern detecting section 6 for generating an initial sync-pattern detecting signal SS and a synchronism establishing signal SE, a de-scramble section 9 for performing de-scramble processing for sector data excluding a sync-pattern after the initial sync-pattern detecting signal or the synchronism establishing signal is generated, and a control section 7 for starting the transfer of sector data for the de-scramble section 9 by inputting the initial sync-pattern detecting signal or the synchronism establish signal and outputting a command signal (a).;COPYRIGHT: (C)1999,JPO
