n 1: (computer science) the time it takes for a read/write head
to move to a specific data track |
seek time
(foldoc) | seek time
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}.

average seek time
(foldoc) | average seek time
The mean time it takes to move the head of a
disk drive from one track to another, averaged over the
source and destination cylinders. Usually measured in
milliseconds (ms).
The average seek time gives a good measure of the speed of the
drive in a multi-user environment where successive read/write
request are largely uncorrelated.
Ten ms is common for a hard disk and 200 ms for an
eight-speed CD-ROM.

maximum seek time
(foldoc) | maximum seek time
(Or full stroke seek time) The time it takes to
seek over all tracks, i.e., from the innermost to the
outermost or vice versa. The maximum seek time gives a
worst-case measure of the speed of the drive which is useful
in some real-time applications where it is important that
data flows continuously (such as video editing or CD
recording).

minimum seek time
(foldoc) | minimum seek time
(Or track-to-track seek time) The time it takes to
move the head of a disk drive from one track to the next.
The minimum seek time gives a good measure of the speed of the
drive in a single-user/single-process environment where
successive read/write request are largely correlated and thus
if correlated data is stored in nearby cylinders most seeks
are from one cylinder to the next.
