Title:
DISK DEVICE
Document Type and Number:
Japanese Patent JP3938861
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To shorten the retry time for executing retry in a disk device.
SOLUTION: In the disk device for executing read/write with respect to an information recording medium according to a command from a host device, when read is executed (S1) and a read error occurs (Y in S2), first of all, the error factor of the generated read error is acquired (S3) and a specified number of times of retry corresponding to the acquired error factor is acquired from a retry table (S4). Then, retry is repeated on the basis of the acquired specified number of times of retry (N in S5) and when retry is repeated to the specified number of times of retry (Y in S5), an error code is transmitted to the host device (S6). Then, the error is reported and read processing is ended. Thus, in the disk device, retry is executed required times suitable for the error factor and useless retry is not executed, so that the retry time can be shortened.
