Detailed explanation-1: -Hard disk drive components include the spindle, disk platter, actuator, actuator arm and read/write head.
Detailed explanation-2: -The read and write arm, also called the actuator arm, is the part of the hard drive that reads data already stored on the platter and writes new data on the platter. The actuator arm includes the read and write heads that float just microns away from the platter that perform the actual read and write tasks.
Detailed explanation-3: -STUDY OF HARD DISK DRIVE The data can be stored on both sides of a disk. Thus there are four read/write heads. The mechanism for the movement of the head can also be seen here. Storage medium in a magnetic-disk system consists of one or more disks stacked on top of one another.
