Veder mooie site die ik ooit eens bezocht heb ivm CD laser technieken.

Kijk bij support/servicetab.

Lees met name ook over de term Red-Book.

Red Book (CD-DA)

Allows for up to 74 minutes of digital sound.
Sample rate of 44.1Khz, or 44,100 samples per second.
Transfer rate of 150 kilobytes per second. Also known as "single-speed" or 1X.
Can contain up to 99 tracks.
Red book audio is also referred to as CD-DA (Compact Disc-Digital Audio). Introduced by Sony and Philips in 1980, the Red Book standard was simply designed to be a universal medium for distributing digitized music.

Data on a audio CD is organized into frames. Each frame contains up to 24 bytes of user data, synchronization, LECC (Logical Error Correction Code), and data for control and display. Frame are interleaved with other frames into a single, spiral so that scratches or defects will not destroy a single frame beyond correction. Rather, a scratch will destroy a small portion of many frames, all of which can be recovered in other frames.

A Red Book disc is divided into three areas: Lead In, Program, and Lead Out. Every track's location is recorded into the disc's TOC (Table of Contents) which is stored in the Lead In area of every disc. The Red Book CD was to become the template for which all other "book standards" were created.
