The mini discs, despite having less weight and plastic, are generally more expensive than full size CD-R/CD-RW discs. Mini CD Replication Manufacturing: Custom-manufactured Mini CDs with integral data are available to the retail market. There are two variations on how the finished product is created:
Comparison of several forms of disk storage showing tracks; green denotes start and red denotes end. Some CD-R(W) and DVD-R(W)/DVD+R(W) recorders operate in ZCLV, CAA or CAV modes. MiniDiscs use rewritable magneto-optical storage to store data. Unlike DCC or the analog Compact Cassette, MiniDisc is a random-access medium, making seek time very ...
The Mini CD has various diameters ranging from 60 to 80 millimetres (2.4 to 3.1 in); they have been used for CD singles or delivering device drivers. The CD gained rapid popularity in the 1990s, quickly outselling all other audio formats in the United States by 1991, ending the market dominance of the phonograph record and the cassette tape.
For example, if a CD-ROM mode 1 image is created by extracting only each sector's data, its size will be a multiple of 2,048; this is usually the case for ISO disc images. On a 74-minute CD-R, it is possible to fit larger disc images using raw mode, up to 333,000 × 2,352 = 783,216,000 bytes (~747 MB).
Photo CD images use three forms of compression in order to reduce image storage requirements. [27] Firstly, chroma subsampling reduces the size of the images by approximately 50%. This subsampling is by a factor of 4 for 4Base images, and a factor of 2 (4:2:0) for all other resolutions.
A CD single is a music single in the form of a compact disc (CD). Originally the CD single standard (as defined in the Red Book) was an 8 cm (3-inch) "mini CD" (CD3); [1] later on the term referred to any single recorded onto a CD of any size, particularly the 12 cm (5-inch) "full-size" disc (CD5).
Dimensions indicated are track pitch (p), pit width (w) and minimum length (l), and laser spot size (⌀) and wavelength (λ). For comparison with analogue media, the pitch of the spiral of a 240-groove-per-inch long-playing record and a Laserdisc are 106 μm (66 times the CD track pitch) and 4.6 μm (2.9 times), respectively.
The CD jewel case is designed to carry a booklet, as well as to have panel inserts. These may be used to display album artwork, lyrics, photos, thank-yous, messages, biography, etc. [5] Because the CD jewel case is the standard, most commonly used CD case, it is much cheaper. The price of the CD jewel case usually ranges from $0.75 to $0.95.
