Structure of removable drive

Internal structure

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 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.
