Study Notes

A magnetic disk consists of platters, read-write heads, and a spindle motor
The platters are rigid disks coated with magnetic material, spinning around the spindle motor
Read-write heads float above the platters to read and write data

A hard drive uses magnetic fields to write and rewrite data on the magnetic disk
The read-write heads use electromagnetic pulses to magnetize tiny areas on the disk
The hard drive accesses data by moving the read-write heads to the correct track and sector
