Abstract
There is disclosed a hard disk drive and an operation method thereof. A method of operating a hard disk drive according to the present invention may include (a) loading drive data required to drive the hard disk drive from a maintenance cylinder area contained in a disk to a memory; and (b) writing test data output from a head into a spare area contained in the maintenance cylinder area, wherein the steps (a) and (b) are carried out within a ready time.
Claims20
A method, comprising:
- (a) loading drive data used for driving a hard disk drive from a maintenance cylinder area of a disk to a memory;
- and
- (b) writing test data output from a head into a spare area of the maintenance cylinder area, wherein the steps (a) and (b) are carried out within a ready time defined between application of power to the drive and the head reaching a target flying height.
An apparatus, comprising:
- a disk comprising a maintenance cylinder area having a spare area and a data area;
- a hard disk controller configured to load drive data used for driving a hard disk drive from the maintenance cylinder area to a memory;
- and
- a head configured to write test data into the spare area contained in the maintenance cylinder area,
- wherein the hard disk controller is configured to write the test data output from the head into the spare area during a ready time defined between application of power to the apparatus and the head reaching a target flying height.

A system, comprising:
- a hard disk drive configured to perform the steps of:
- (a) loading drive data used for driving the hard disk drive from a maintenance cylinder area of a disk to a memory;
- and
- (b) writing test data output from a head into a spare area of the maintenance cylinder area, wherein the loading step and the writing step are carried out in full before the head reaches a target flying height;
- and
- a host configured to control the hard disk drive.
