摘要： A technique for controlling a group of logic included in a hard disk drive system, is performed by obtaining an access instruction associated with accessing a target location in a disk included in the hard disk system. A number of units until the target location is accessed is calculated. It is determined whether to put the group of logic into a lower power state based at least in part on the number of units until the target location is accessed and a warm up time associated with the group of logic; in the event it is determined to do so, the group of logic is put into the lower power state.

摘要： A length of a separator to be skipped on the storage disk is compared with a threshold. The threshold is associated with a maximum value for which a timing loop is able to be paused without causing the timing loop to have inaccurate timing. If the length is greater than the threshold, a first split sector format is assigned to the split sector and that information is recorded. In such cases, a first portion and a second portion both include synchronization information. If the length is less than the threshold, a second split sector format is assigned to the split sector and that information is recorded. In such cases, the first portion includes synchronization information and the second portion of the split sector excludes synchronization information.

摘要： An access instruction associated with accessing a target location in a disk is obtained. A number of units until the target location is accessed is calculated. It is determined whether there is time for the group of logic to transition from a lower power state to an operational state; the determination is based at least in part on the number of units between a current location of a read head associated with the hard disk system and the target location which is different from the current location of the read head and a warm up time associated with the group of logic. If it is determined there is time, the group of logic is put into the lower power state.

摘要： User level data associated with a location adjacent to a desired location on a magnetic disk storage is received. Media level data associated with the adjacent location is generated based at least in part on the user level data associated with the adjacent location; a processor which is configured to generate the media level data associated with the adjacent location is a same processor which is configured to generate media level data based at least in part on user level data during a write process. The media level data associated with the adjacent location is used to remove inter-track interference (ITI) associated with the adjacent location from a signal read back from the desired location.
