Claims11
A disk drive comprising:
- a disk having a plurality of concentric tracks used as data-recording areas;
- a head configured to read data from the disk, and write data in the disk;
- a flash memory configured to store data;
- and
- a controller configured to control the reading of data from the disk, the writing of data in the disk, and the writing of data in the flash memory,
- wherein the controller is configured to determine whether requested data transmitted from a host system for recording in the disk is continuous data to be written in at least two adjacent tracks of the disk specified by consecutive addresses, configured to store the first one-track data item comprising the head address of the requested data in the flash memory when the requested data is the continuous data, and configured to sequentially write the second to last one-track data items in the disk.
