Address assigning method, disk drive and data writing method

摘要

To enable a disk drive of an address system wherein track groups of different track widths are discretely disposed on the storage medium in a same disk drive and the dimensional relationship among physical block addresses of a sector is valid for the dimensional relationship among logical block addresses to write data normally. Manage track groups corresponding to their respective track width in the disk drive and dispose successively in the logical block address space the respective track groups located discretely on the physical block address space. If there are two track groups called Shingled Tracks (ST) and Tiled Tracks (TT), in the step 1110 depending on which of the ST region and the TT region the sector to be accessed is located, execute respectively the steps 1111 through the steps 1116 or the step 1117 through the step 1118 and translate the logical block addresses into the physical block addresses.
