3.5-inch and 5.25-inch drives connect to the floppy controller using a 34-conductor flat ribbon cable for signal and control. Most controllers support two floppy drives, although the Shugart standard supports up to four drives attached to a single controller. A cable could have 5.25-inch style connectors, 3.5-inch style connectors, or a ...
When the controller and disk drive are assembled as one device, as it is the case with some external floppy disk drives, e.g., Commodore 1540 and USB floppy disk drives, [27] the internal floppy disk drive and its interface are unchanged, while the assembled device presents a different interface such as IEEE-488, parallel port or USB.
A disk controller is a controller circuit that enables a CPU to communicate with a hard disk, floppy disk or other kind of disk drive. It also provides an interface between the disk drive and the bus connecting it to the rest of the system. [1] [2] Early disk controllers were identified by their storage methods and data encoding.
Many types of Berg connectors exist. Some of the more familiar ones used in IBM PC compatibles are: the four-pin polarized Berg connectors used to connect 3½-inch floppy disk drive units to the power supply unit, usually referred to as simply a "floppy power connector", but often also referred to as LP4. This connector has a 2.50 mm (0.098 in ...
The ST-506 and ST-412 (sometimes written ST506 and ST412 [1]) were early hard disk drive products introduced by Seagate in 1980 and 1981 respectively, [1] that later became construed as hard disk drive interfaces: the ST-506 disk interface and the ST-412 disk interface. Introduced in 1980, the ST-506 was the first 5.25 inch HDD.

A data cable (top) and control cable (below) connecting a controller card and an ST-506 type HDD. Power cable not shown. The earliest hard disk drive (HDD) interfaces were bit serial data interfaces that connected an HDD to a controller with two cables, one for control and one for data.
The 1541 was the standard floppy disk drive for the Commodore 64, with nearly all disk-based software programs released for the computer being distributed in the 1541 compatible floppy disk format. The 1541 was very slow in loading programs because of a poorly implemented serial bus , a legacy of the VIC-20 .
