The Commodore 1541 (also known as the CBM 1541 and VIC-1541) is a floppy disk drive created by Commodore International for the Commodore 64 (C64), Commodore's most popular home computer. The most famous floppy disk drive for the C64.
The 1541 is a single sided 170 kilobyte drive for 5¼ "floppies.
The disk drive uses group coded recording (GCR) and contains a MOS Technology 6502 microprocessor, doubling as a disk controller and on-board disk operating system (DOS) processor. The number of sectors per track varies from 17 to 21 (an early implementation of zone bit recording). The drive's built-in disk operating system is CBM DOS 2.6.
