Hard Disk Drive

• Hard Drive is considered to be one of the
  most relevant parts of a computer. It is
  basically used to store files and valuable data
  into the computer. It was first introduced by IBM
  on September 13, 1956.

• A computer user needs a hard drive for storing
  data and program files. Nowadays along with
  internal hard drive, external hard drive has
  become equally popular. Here some few example of
  relevant external hard drives like IBM 2TB hard
  drives, HP 652564-B21 hard drive etc.

• Hard Drive consist of six components
• Head actuator
• Read/Write actuator
• Read/Write head
• Spindle
• Platter
• Disk controller

6

• Actuator
• It is an electronic device, which is
  maintained by a motor that moves the hard drive
  head arm.

7

• Actuator arm
• Actuator arm, also known as the access arm it
  performs the operation of reading and writing
  data to the platter by utilizing its read/write
  head which stretches out over the platter.

8

• Platter
• The discs which are placed one above the other
  are known as platters. It is basically made up of
  ceramic and aluminum materials . It is capable of
  holding large amount of data.

• Read/Write head
• A read/write head performs the task of reading
  data from the hard drive's disk platter.
• Spindle
• It holds the hard drives platter in a fixed
  position.

The process of reading and writing data on a hard
drive

• Disk controller is responsible for
  interpreting the data which are sent to and from
  the computer. Whenever you open a file on your
  computer for editing, the disk controller
  instructs actuator to move the read/write arm and
  align the read/write head.

• After editing the file when you click on the
  save option the arm use its write heads to
  overwrite the previous file. Now a days some hard
  drives operate at a speed of 7,200 rpm.
