Example part numbers are any of TE Connectivity / AMP 170204-* (loose pieces) or 170262-* (pieces supplied in strips), where * is 1 or 2 or 4. [2] [3] The male PCB connector on the 3½-inch floppy drive is normally a polarized right-angle male header, which is a TE Connectivity / AMP 171826-4, [4] the straight model is AMP 171825-4. [5]
The cable is normally a ribbon cable. For IBM-compatible floppy controllers, a twist in the cable reverses the order of conductors 10 through 16 for the second connector. This allows two drives connected to the same cable to be addressed by the host controller without having to select drive assignments with jumpers on the drives themselves ...
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.
The desktop computer hard-drive connector (AMP Mate-n-Lok 1-480424-0 power connector) is standard on all 5.25-inch floppy drives, 3.5-inch PATA and non-SCA SCSI disk drives; however, newer SATA disk drives employ a more advanced interconnection with 15 contacts. These advanced connection systems were first developed by Molex and other connector ...
The original Bernoulli Alpha drive spins a PET film floppy disk at about 1500 rpm, [1] 1 μm over a read-write head, using Bernoulli's principle to pull the flexible disk towards the head as long as the disk is spinning. In theory this makes the Bernoulli drive more reliable than a contemporary hard disk drive, since a head crash is impossible.
A ribbon cable is a cable with many conducting wires running parallel to each other on the same flat plane. As a result, the cable is wide and flat. Its name comes from its resemblance to a piece of ribbon. [1] Ribbon cables are usually seen for internal peripherals in computers, such as hard drives, CD drives and floppy drives.
8-inch floppy disk, inserted in drive, (3½-inch floppy diskette, in front, shown for scale) 3½-inch, high-density floppy diskettes with adhesive labels affixed The first commercial floppy disks, developed in the late 1960s, were 8 inches (203.2 mm) in diameter; [4] [5] they became commercially available in 1971 as a component of IBM products and both drives and disks were then sold ...
Hub (engages with the drive motor). Shutter (protects the surface when diskette is removed from the drive). Plastic housing (the external case). Paper ring (a polyester sheet reducing friction against the disk media as it rotates within the housing). Magnetic disk (the magnetic coated plastic disk).
