Value

Meaning

CD_IDENTIF_TEXT

0

Retrieves the CD-Text information.

CD Text is a technology developed by Sony Corporation and Philips Electronics in 1996 that allows storing information about an audio CD and its tracks (such as artist name, album, or song name) directly on the disk. Currently, many commercially available audio CDs contain CD Text information.

If CD Text is written on a CD, it is no need to query Internet databases for artist name or track list. CD-Text Reader delivers this information fast and right from the disk. No typos or misspelled names: the information comes directly from the publisher.

CD-Text is still not available on the majority of CDs.

CD_IDENTIF_CDDB

Retrieves a CDDB identifier that can be used to get details on the CD from a CDDB server. Refer to the documentation available on the http://www.cddb.com and http://www.freedb.org web sites for more information on using a CDDB server.

CD_IDENTIF_MS

2

Retrieves an identifier, usually adopted by Windows Media Player, that can be used to get details on the CD from a Microsoft server.

CD_IDENTIF_UPC

3

Retrieves the catalog number of the CD. The number is an UPC/EAN barcode. This information might not be available for all CDs.
