sorry for the beginner question.

I am learning about how fast a disk can do its process (read/write) and move between tracks. One if the factor related to this is disk's seek time.

I am curious, in a disk, what factors in the disk itself that can affect the seek time?

Three things:

  1. The distance traveled from One track to another.
  2. The head settlement time once it reaches the correct track.
  3. The rotation delay until the sector to be read or written comes under the disk head.

  • this applies only to magnetic spindle disks

  • @Keltari I would say this applies to any rotational disk; HDD, CD, DVD, Floppy, Blu Ray, Etc. Do they have holographic disks yet?
