1. a variant spelling (esp US and Canadian) of disc
2. (Computer Science) computing Also called: magnetic diskorhard disk a direct-access storage device consisting of a stack of plates coated with a magnetic layer, the whole assembly rotating rapidly as a single unit. Each surface has a read-write head that can move radially to read or write data on concentric tracks. Compare drum19 See also floppy disk
Usage Have you ever noticed that when you buy a music CD, it is a compact disc, but when you buy a CD in a computer store it is usually a compact disk? Sometimes spelling varies according to how a word is used. Back in the late 19th century, when people were developing the technology for recording sound on a flat plate (what later became the vinyl phonograph record), the inventors referred to the plates as discs, using an alternate spelling of disk. The c spelling eventually became prevalent in the music industry, known for its disc jockeys. When American computer scientists developed flat storage devices back in the 1940s, they chose the common American spelling disk, and this is why we have hard disks installed on our computers. When the storage device known as the compact disk was invented, people in the music industry saw them as shiny substitutes for phonograph records, and they referred to them as compact discs, despite the fact that these same discs were compact disks when they stored nonmusical data. One of the advantages of abbreviations like CD is that they make spelling much simpler!
diskette, floppy, floppy disk - a small plastic magnetic disk enclosed in a stiff envelope with a radial slit; used to store data or programs for a microcomputer; "floppy disks are noted for their relatively slow speed and small capacity and low price"

Triangular fibrocartilage complex (TFCC) is composed of multiple distinct anatomic structures including the triangular fibrocartilage (TFC, the articular disk), meniscal homolog (MH), dorsal and volar distal radioulnar ligaments, the extensor carpi ulnaris tendon (ECU), ulnar collateral ligament (UCL), ulnotriquetral (UT) ligament, and the ulnolunate (UL) ligament.[sup], The TFCC is the main stabilizer of the ulnar-sided wrist and the distal radioulnar joint (DRUJ).
(2) TFCC consists of the triangular fibrocartilage (TFC or articular disk), meniscal homologue, ulnocarpal [ulnolunate (UL) and lunotri quetral] ligaments, the dorsal and volar radio ulnar ligaments, ulnar collateral ligament, and the extensor carpi ulnar is (ECU) sub sheath.
