Hard drive components

I want to continue the matter and, on the hard disk. Now I want to discuss about the components of the hard disk. Hard drive consists of its constituent components, which include the following:

a.) Metal disc (Platter) which serves as data storage. This disc was given layer is very thin magnetic materials.

b) Head, in the form of coils. Head on a different hard drive with a head on Tape. On Tape process read & write (record) using two heads, while the hard drive that process uses the same head.

c) electronic circuit in the PCB (printed circuit board), which consists of:

* Amplifier circuit
* DSP (Digital Signal Processor)
* Memory Chip
* Connectors
* Spindle and Actuator arm Monitor

Now that he's components. Wait again next posting ..!!!
