摘要:
According to one embodiment, a disk drive includes a disk and a data read/write module. The disk has a disk substrate, tracks and non-recording areas. The tracks and the non-recording areas are formed on the disk substrate and arranged in the radial direction of the disk. The tracks are magnetic layers and have a recording area each. The non-recording areas are made of non-magnetic layers and arranged between the tracks. Thus, valid recording area and invalid recording areas are provided in each track, at a predetermined ratio. The data read/write module is configured to write data in or read data from the valid recording areas, but not in or from the invalid recording areas.
