STORAGE DEVICE, CONTROL DEVICE FOR STORAGE DEVICE, METHOD FOR CONTROLLING STORAGE DEVICE, AND PROGRAM

摘要

A storage device (100) has a disc (110) containing a plurality of tracks (111) on which data can be recorded, a head (120) driven from an origin point over the tracks (111) on which data is recorded when data is to be read out from the disc (110), and a controller (130) for driving the head (120). The controller (130) executes a retry for again driving the head (120) over the tracks (111) on which data is recorded to read out the data from a base point other than the origin point when an error has occurred in reading out the data.
