| A computer's main
storage media device, also called a hard disk drive or
abbreviated as HD or HDD. The hard drive was
first introduced on September 13,
1956 and consists
of one or more hard disk platters inside of air
sealed casing. Most hard drives are permanently stored in an internal
drive bay at
the front of the computer and are connected with either ATA, SCSI, or a SATA cable and power cable. Below is an illustration
of the inside of a hard disk drive.
As can be seen in the above picture of the desktop hard drive the main six components that help make up the inside are the head actuator, read/write actuator arm, read/write head, spindle, and platter.
