Disk drive and method of controlling the same
First Claim
1. A disk drive comprising:
- a disk medium;
a head configured to perform a read/write operation for accessing the disk medium to read information from and to write information to the disk medium;
a head controller configured to control the position of the head so that the head describes a substantially spiral trajectory relative to the surface of the disk medium; and
a controller configured to control the head controller, perform a read/write operation for writing or reading information with reference to an identifier table associating sector identifiers identifying sectors on an accessed track with logical block addresses, and create an identifier table for a track to be accessed next during the read/write operation.

Abstract
Embodiments of the invention provide a disk drive capable of preventing the deterioration of performance. In one embodiment, a disk drive includes a disk medium; a head capable of performing a read/write operation for accessing the disk medium to read information from and to write information to the disk medium; a head controller for controlling the position of the head so that the head describes a substantially spiral trajectory relative to the disk medium; and a controller capable of controlling the head controller, of performing a read/write operation for reading or writing information with reference to an identifier table associating sector identifiers identifying sectors on a specified track with logical block addresses, and of creating an identifier table for a track to be accessed next during the read/write operation.

6. A method of controlling a disk drive including a disk medium, and a read/write head capable of accessing the disk medium to carry out a read/write operation, said method comprising:
-
controlling the position of the read/write head such that the read/write head describes a substantially spiral trajectory relative to the disk medium;
performing a read/write operation to write information to or read information from an accessed track with reference to an identifier table associating identifiers identifying sectors on the track with logical addresses; and
creating an identifier table for a track to be accessed next during the read/write operation. - View Dependent Claims (7, 8, 9, 10)
