Question

The heads of the magnetic disk are attached to a _____ that moves all the heads as a unit.

a) spindle
b) disk arm
c) track
d) None of these

Answer 1

The heads of the magnetic disk are attached to a disk arm, which moves them as a unit to access various tracks on the disk.

Step-by-step explanation:

The heads of the magnetic disk are attached to a device known as a disk arm. This disk arm moves all the heads as a unit, allowing them to access different tracks on the magnetic disk where data is stored. While a spindle is involved in the operation of a hard disk drive, its role is to spin the disks themselves, not to move the heads.

A track is actually one of the concentric circles on the disk that the heads read from or write to, not the part that moves the heads.The heads of the magnetic disk are attached to a disk arm, which moves them as a unit to access various tracks on the disk.
