A view of a CD-ROM drive's disassembled laser system The movement of the laser enables reading at any position of the CD. The laser system of a CD-ROM drive. CD-ROM discs are read using CD-ROM drives. A CD-ROM drive may be connected to the computer via an IDE , SCSI, SATA, FireWire, or USB interface or a proprietary interface, such as the ...
CD-i discs can contain audio tracks that can be played on regular CD players, but CD-i discs are not compatible with most CD-ROM drives and software. The CD-i Ready specification was later created to improve compatibility with audio CD players, and the CD-i Bridge specification was added to create CD-i-compatible discs that can be accessed by ...
Eugen Pavel is a Romanian scientist and the claimed inventor of the Hyper CD-ROM.. Pavel graduated with a physics degree from the University of Bucharest in 1976. [1] He was awarded the Romanian Academy Prize in 1991 and obtained his doctorate in Physics from the Romanian Institute of Atomic Physics in 1992.
In 1983, following the CD's introduction, Immink and Braat presented the first experiments with erasable compact discs during the 73rd AES Convention. [33] In June 1985, the computer-readable CD-ROM (read-only memory) was introduced and, in 1990, the CD-Recordable, also developed by both Sony and Philips. [34]
The CD-ROM format was developed by Sony and Denon, introduced in 1984, as an extension of Compact Disc Digital Audio and adapted to hold any form of digital data. The CD-ROM format has a storage capacity of 650 MB. Also in 1984, Sony introduced a LaserDisc data storage format, with a larger data capacity of 3.28 GB. [59]
The Hyper CD-ROM is a claimed optical data storage device similar to the CD-ROM with a multilayer 3D structure, invented by Romanian scientist Eugen Pavel. The technology is supposedly similar to FMD discs. The bit of data being held as a change in fluorescence characteristics once irradiated with one or two lasers.
A CD player is an electronic device that plays audio compact discs. CD players are often a part of home stereo systems, car audio systems, and personal computers. They are also manufactured as portable devices. Modern units can play other formats in addition to PCM audio coding used in CDs, such as MP3, AAC and WMA.
However, CDs have grown to encompass other applications. In 1983, following the CD's introduction, Immink and Joseph Braat presented the first experiments with erasable compact discs during the 73rd AES Convention. [50] In June 1985, the computer-readable CD-ROM (read-only memory) and, in 1990, recordable CD-R discs were introduced.
