What is R/W Head?
R/W Head (Read/Write Head). A small electromagnetic device that reads data from and writes data to the magnetic surface of a hard disk drive, converting digital information to magnetic patterns and vice versa.
Simply Put:
A R/W Head is like the needle on a record player. It moves over the disk to read the music or write new sounds, except it handles data instead of songs.
