Question

Difference between fixed head disk and movable head disk

Answer 1

Fixed head/Movable head disks: The disks in which the head do not move are called fixed head.

On the movable head disk normally we have one read/write head which is fitted on an arm. This arm allows head to position on any track of the platter.

Answer 2

Answer:

Fixed head/Movable head disks:

The disks in which the head do not move are called fixed head. For such disks we require cite read/write head per track. Heads can be mounted on a rigid arm which extends to the centre of the disk. On the movable head disk normally we have one read/write head which is fitted on an arm. This arm allows head to position on any track of the platter.

Removable and Non-removable Disks: The disks are normally mounted in a disk drive which consist of an arm and a shaft along with the shaft. A non-removable disk is permanently mounted on the disk drive. Example of a non-removable disk is the hard disk of a PC-AT. The removable disks can be replaced by another similar disk on to same or different computer, thus, providing enormous data storage which is not limited by the size of the disk. Example of such disks are floppy diskettes.
