caption_attribution_description: The Commodore 1541, the official 5¼" floppy drive for the Commodore 64 8-bit home computer. Introduced in 1982, the drive retailed for $400 at launch.
context_page_description: The Commodore 1541 is a floppy disk drive which was made by Commodore International for the Commodore 64, 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.
  The disk drive uses group coded recording and contains a MOS Technology 6502 microprocessor, doubling as a disk controller and on-board disk operating system processor. The number of sectors per track varies from 17 to 21. The drive's built-in disk operating system is CBM DOS 2.6.
context_section_description: 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 (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.
caption: Front view of the second-most common version of the Commodore 1541 disk drive, with open disk slot. This version uses a Newtronics drive mechanism, and the rotating lever is used to engage the drive mechanism with the disk (i.e. to engage the hub clamp and load the disk heads) and to prevent removal of the disk while the mechanism is mechanically engaged.
