Access arm

Posted on Monday, September 22, 2014 by Unknown


Alternatively referred to as read/write head arm, head arm, or actuator arm, the access arm is in every mechanical hard drive; similar in appearance to the arm of a record player. As the platter spins, the access arm adjusts the read/write heads to facilitate the reading, writing, or deletion of information. The image shows the inside of a hard drive.
