[Needs editing: copied from thesis Robust and fault-tolerant control of CD players]In 1972 Philips announced a technique for storing data on an optical disc . Philips and Sony were the first to propose the Compact Disc Digital Audio (CD-DA) standard in 1981, which was codified in the so-called Red Book [Philips and Sony Corporation, 1991]. The development of this technique revolutionized the world of audio by introducing true digital technology for the first time. It was in 1982 that Philips and Sony launched the first players and discs on the market. The CD became the music medium of choice in 1991, when sales surpassed those of audio cassettes. Another widely available optical disc technology is Digital Video/Versatile Disc, abbreviated to DVD. While a CD can hold 650[MB] or 700[MB] of data, a DVD can hold up to 25 times more. There is also another type of optical discs, the so-called high-capacity optical discs, which are characterized by offering the user storage capacities typically between 20[GB] and 50[GB], (approximately between 30 and 75 times more data compared to a CD). At the time of writing, four high-capacity optical discs have been announced: Blu-ray Disc (BRD) [Hitachi et al., 2002], Advanced Optical Disc [Toshiba and NEC, 2002], Blue-HD (High Density) [OES and AOSRA, 2002] and the HD-DVD-9 disc [Bros, 2002]. In principle they are all rewritable discs, although ROM versions are being discussed. Since the first CDs printed for mass replication were introduced to the market, a confusing number of optical disc formats have been developed that give the consumer the ability to not only read data but also record and erase as desired. The many standards and formats of optical discs can be divided into three g...... half of the paper ...... the correction code used in DVDs, called the Reed-Solomon (RS) product code, capable of correct a burst length of approximately 6[mm]. The deinterlave process is achieved by sequentially writing to a data buffer and reading via a sequencer. The speed of the disk motor is not important and the system drives the spindle at the necessary speed so that the data buffer does not go over or under. The size of the data buffer is a trade-off between economic costs and resistance to burst errors. Why optical disc drive? In recent years, the optical disc drive has become one of the main data storage devices in auxiliary storage devices and AV systems. The reasons for this popularity are the short access time compared to that of magnetic tape drives, the interchangeability of the disks and the almost unlimited lifetime [New Fine Seek control for optical disk drives]
