Title:
媒体記憶装置のデータ消失防止方法及び媒体記憶装置
Document Type and Number:
Japanese Patent JP4751131
Kind Code:
B2
Abstract:
A media storage device reads and writes data from and to a storage medium using a head and prevents in advance data loss due to thermal relaxation of data recorded on the storage medium. Table stores information which is related to a read error detected by a channel circuit in record units. The channel circuit measures information which is related to a read error and updates the information in the table. Further, data degradation is judged by this information which is related to the read error. Degradation of recorded data due to thermal relaxation can be detected accurately, and data loss can be prevented.
