Define access time for magnetic disk, Computer Engineering

Define access time for magnetic disk.

The sum of seek time and rotational delay is known as access time for disks.

Seek Time:

Seek time is the time needed to move the read/write head to the proper track.

Rotational latency:

Rotational latency is the amount of time that elapses after the head is positioned over the correct track unless the stating position of the addressed sector passes under the read/write head.
