The time required for the access mechanism of a random-access storage device to be properly positioned.

seek time

(storage)
The time it takes for a disk drive to move its head(s) from one track to another. The seek time depends on the power of the servo, the mass of the heads, the number of tracks traversed and the time taken to position the heads over the target track accurately enough to start data transfer.

See also: average seek time, minimum seek time, maximum seek time.

seek time

The average of the time it takes to move the read/write from its current location to a particular track on a disk. In 1998, Seagate introduced its line of Cheetah hard disks with 5ms seek time. Ten years later, it was down to an average of 3.9ms. See access time.

The ConQuest CD-ROM engine collects all dictionary and index information for a word into a single location, so that one disk seek will get all the necessary data: 1) the word, 2) morphological variations of the word, 3) expansions of the word, 4) top-level index information for the word, 5) pointers to the lower-level index information for the word.
ConQuest has developed a dedicated CD-ROM engine architecture, designed to optimize performance in the CD-ROM environment by reducing the number of disk seeks.
By design, disk seeks need to be avoided as much as possible, as they are expensive operations.
