Q. Explain about hard drives?
Disks are generally mounted on a disk drive which comprises of an arm and a shaft along with electronic circuitry for read-write of data. Disk rotates along with shaft. A non-removable disk is permanently mounted on disk drive. One of most significant illustration of a non-removable disk is hard disk of PC. Disk is a platter coated with magnetic particles. Early drives were large. Later on smaller hard (rigid) disk drivers were created with fixed and removable pack. Every pack held about 30MB of data and became called as the Winchester drive. Storage capacity of today's Winchester disks is typically of order of a few tens of Megabytes to a few Gigabytes. Most Winchester drives have subsequent common aspects:
(a) An Open Disk Casing
(b) Tracks and Cylinders
