Structure of removable drive
The removable disk drive is composed of a magnetic platter, which is a circular metal platter consisting of many hard disks made of aluminum or glass-ceramic compounds. The discs are coated with a magnetic or protective layer on both sides, stacked on top of each other and attached to a rotating shaft.
That is why the discs are rotated at the same speed throughout the session, ensuring the best performance.
Disc and head construction
– The read-write head is on each side of the disc, which is responsible for recording data during use. The number of disks on the hard drive corresponds to the number of read and write heads, for example, if a drive has 2 corresponding disks, there will be 4 read – write heads.
– The motor or coil drives the magnetic heads to support the heads to move horizontally on the surface of the disk so that they can write – read data.
– The control circuit is located right behind the hard disk, doing the following tasks:
- Controls the rotational speed of the disk in the hard drive.
- Move the heads during reading and writing of data.
- Encrypt information and decrypt data received from the computer.
– The surface structure of the disk is the main storage place for data when the hard drive starts to work, with the heads performing the task of moving, reading and writing data.
