Magnetic disk apparatus and method for accessing data sector
A magnetic disk apparatus includes a disk and a controller. The disk includes a plurality of tracks including a first track and a second track that is different from the first track. A plurality of data sectors are located on the tracks. The data sectors include short data sectors and long data sectors, each including a plurality of short data sectors. If the controller accesses a long data sector located at an end of the first track, the controller first accesses a short data sector of the long data sector at the end of the first track, and then accesses a short data sector of the long data sector at the beginning of the second track.
