Topic: CD-ROM |
| When Sony and Philips invented the Compact Disc (CD) in the early 1980s, even they couldn't ever have imagined what a versatile carrier of information it would become. Launched in 1982, the audio CD's durability, random access features and audio quality made it incredibly successful, capturing the m... |

Topic: CD-ROM |
| Then there's the question of which applications actually benefit from a faster CD-ROM drive. Most multimedia titles are optimised for double or, at best, quad-speed drives. If video is recorded to play back in real time at a 300 KBps sustained transfer rate, anything faster than double-speed is unne... |

Topic: CD-ROM |
| Traditionally, CD-ROM drives have used Programmable Input Output (PIO) rather than Direct Memory Access (DMA) for data transfer. This was favoured for the earlier designs because hardware implementation is simpler and adequate for devices that require low transfer rates. The drawback is that the CPU... |

CD-ROM - part 4 by MDofPC |
Topic: CD-ROM |
| Confusion reigned temporarily when Philips put MPEG-1 video on Green Book discs, which could only be played on CD-i machines. However, all new MPEG-1 film titles conform to the White Book standard for Video CDs, which may be read on any White Book-compatible machine including CD-i and suitable CD-RO... |

CD-ROM - part 5 by MDofPC |
Topic: CD-ROM |
| The term "premastering" is often used quite broadly, to refer to all of the steps which proceed the first stage in the manufacturing process proper. Strictly, data preparation, indexing, testing (also called simulation), and creating the "image" are actually performed before premastering. The encodi... |

Topic: CD-ROM |
| The basic CD-ROM (Compact Disc - Read Only Memory) is 120mm in diameter and is basically a 1.2mm sandwich of three coatings: a back layer of clear polycarbonate plastic, a thin sheet of aluminium and a lacquer coating to protect the disc from external scratches and dust. |

Topic: CD-ROM |
| Apart from far more sophisticated error-checking techniques, the innards of a CD-ROM drive are pretty much the same as those used in CD audio players. Data is stored in the same way on all CDs. |

CD-ROM - part 8 by MDofPC |
Topic: CD-ROM |
| On vinyl and audio cassettes, the audio waveform is recorded as an analogue signal. Therefore any imperfections will be heard as noise (hiss) or other defects. To reduce these defects, CDs use digital techniques, storing "samples" as numbers. |
