The '''Commodore 1541''' (also known as the '''CBM 1541''' and '''VIC-1541''') is a [[floppy disk drive]]  which was made by [[Commodore International]] for the [[Commodore 64]] (C64), Commodore's most popular [[home computer]]. The best-known floppy disk drive for the C64, the 1541 is a single-sided 170-[[kilobyte]] drive for 5¼" disks. The 1541 directly followed the [[Commodore 1540]] (meant for the [[VIC-20]]).

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]] processor. The number of [[disk sector|sectors]] per [[track (disk drive)|track]] varies from 17 to 21 (an early implementation of [[zone bit recording]] with 4 [[ZCAV|constant angular velocity zones]]). The drive's built-in disk operating system is [[Commodore DOS|CBM DOS 2.6]].
