It is used to rotate the actuator. It Moved by Stepper motor or voice coil.
HARD DRIVE:-
It is used to store memory in magnetic form.It rotate at high speed 5200 to 7200 rmp (Rotation per minute) A hard disk drive is a non-volatile storage device that stores digitally encoded data on rapidly rotating rigid Platters with magnetic surfaces. Strictly speaking, "drive" refers to the motorized mechanical aspect that is distinct from its medium, such as a floppy disk drive and its floppy disk. Early HDDs had removablemedia; however, an HDD today is typically a sealed unit with fixed media.
ACCUTATOR:-
The actuator has a read-write head at the end of actuator and under the tip. A thin printed-circuit cable connects the read-write head to the hub of the actuator.
SPLINDER:-
There is a one head for each megnatic platter surface on the splindle.A typical HDD design consists of a spindle that holds the circular disks. The HDD's spindle system relies on air pressure inside the disk enclosure to support to disk rotate.
RUBBER SHOCK:-
When the hard disk is rotating at that time vibration is occurred.so, it useful to Absorb the vibration of the hard disk and increased hard disk’s life.
LOCKING LETCH:-
A latch is provided suitabl for forcing the the drive intoor out of engagement with the
computer against resistance from mounting guide rails and an electrical connector. The latch is also suitable for locking the drive securely in place when it is in use and for carrying the drive between computers.
