Abstract
According to one embodiment, a disk drive that includes a disk and a disk controller is provided which effectively correct data errors that are generated at the time of reproducing data. The disk has a data-recording area constituted by a set of magnetic dots that are physically separated from one another. The disk controller uses error-correcting codes to determine an error that shows a change in the total number of bits in a data-bit string of the data set reproduced.
