Read write head hard drive
A disk read-and-write head is the small part of a disk drive which moves above the disk platter and transforms the platter's magnetic field into electrical current (reads the disk) or, vice versa, transforms electrical current into magnetic field (writes the disk). The heads have gone through a number of changes over … See more Inductive heads use the same element for both reading and writing.

In case of any malfunction, drop or shake, read/write heads can touch the platters and damage themselves and the platter. That means the read/write head is unable to perform its tasks. This results in clicking inside of your hard disk.
