Disk device, disk control method, data read and write methods, data placement methods and the disk-shaped storage medium

摘要

PROBLEM TO BE SOLVED: To provide a disk drive, disk control method, data reading/writing method, data arranging method, and a disk-like storage medium, which are capable of preventing a nonlinear movement or the increase of the friction of a bearing even though the width of one track becomes further narrower. SOLUTION: In the magnetic disk 11 of a disk drive device 10, LBAs(logical block addresses) are read/written in such a manner that a 1st track including a specified number of continuous LBAs, a 2nd track including a specified number of continuous LBAs in succession of the specified number of continuous LBAs, and at least one track between the 1st track and 2nd track are provided when n pieces of LBAs are included per one track, and in a control part 22, the seek operation is carried out so that the track to read/write the next data is to be the track separated more than one track at least when the continuous data are read/written by moving the track.
