WHAT IS A HARD DRIVE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The actuator or head actuator is a huge motor that takes instructions from the circuit board of the drive
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The actuator or head actuator is a small motor that takes instructions from the drive’s circuit board to control the movement of the read/write arm and supervise the transfer of data to and from the platters. It’s responsible for ensuring the read/write heads are in exactly the right place at all times.

Detailed explanation-2: -Actuator: The actuator is responsible for moving actuator arms which hold the read/write heads precisely with a specific track and sector. The actuator is one of the most important parts of the hard drive that determine the speed of the drive and how many bits it can pack on its platters.

Detailed explanation-3: -An actuator is an electronic device controlled by a motor that moves the hard drive head arm. In the past, the actuator within a hard drive was controlled by a stepper motor. However, today the actuator is often controlled by a servo motor.

Detailed explanation-4: -Hard Disk Drive (HDD) spindle motors are what cause the disks in HDDs to rotate. The precision of these motors determine the capacity and speed of HDDs, making these components critical to HDD performance.

Detailed explanation-5: -The DC Motor or Direct Current Motor to give it its full title, is the most commonly used actuator for producing continuous movement and whose speed of rotation can easily be controlled, making them ideal for use in applications were speed control, servo type control, and/or positioning is required.
