Abstract
A system and method within a hard disk drive for transferring track sector information of a storage disk to a memory device. The system of the present invention includes a disk having multiple tracks, wherein each of the tracks includes at least one sector. The system further includes a memory device for storing sector identification data and user data. A drive data bus is utilized for transferring data between the storage disk and the memory. A controller is utilized to manages read and write operations to and from the storage disk, wherein the controller includes means for selecting either said user data or said sector identification data to be transferred to said memory device.
Claims12
A system within a hard disk drive for transferring track sector information of a
- storage disk to a memory device, said system comprising:
- a disk having a plurality of tracks, wherein each of said plurality of tracks includes at least one sector;
- a memory device for storing sector identification data and user data;
- a drive data bus for transferring data between said storage disk and said memory;
- and
- a controller that manages read and write operations to and from said storage disk, wherein said controller further comprises means for selecting either said user data or said sector identification data to be transferred to said memory device, and wherein said controller further comprises a bus selector for switching said drive data bus between said user data and said sector identification data in response to a table update signal.
A method within a hard disk drive for transferring track sector information of a storage disk to a memory device, wherein said hard disk drive includes a disk having a plurality of tracks, wherein each of said plurality of tracks includes at least one sector, said method comprising:
- storing sector identification data and user data;
- transferring data between said storage disk and said memory;
- and
- controlling read and write operations to and from said storage disk, wherein either said user data or said sector identification data is selected to be transferred to said memory device in response to a table update signal.
