摘要： A disk drive is disclosed which receives a plurality of access commands from a host, where each access command identifies a target track. The access commands are stored in a command queue, and for each command in the command queue, a seek length is computed corresponding to a number of tracks between a current track the head is over and the target track of the access command. A seek time is computed in response to the seek length using a seek profile comprising a first plurality of seek length segments and a variance group comprising a second plurality of seek length segments. Each seek length segment corresponds to a range of seek lengths, and the first plurality of seek length segments is different than the second plurality of seek length segments.

摘要： A disk drive is disclosed comprising a disk, a head actuated over the disk, and a history array for storing a plurality of history records, wherein each history record having a history range identifying a range of sector addresses proximate the sector address of a host command. As new host commands are received, the sector address of each host command is compared to the history records in the history array. A counter is adjusted in response to each comparison, and an operating mode of the disk drive is configured into a new operating mode if the counter exceeds a threshold, wherein the configuring includes adjusting at least one of the history range and the threshold relative to the new operating mode.
