DLA is used to make file archives and data CDs that can be altered many times. It also provides the convenience of direct drive-letter access. When used with CD-RW media, DLA is very much like using a floppy diskette to store files. If DLA is used with CD-R media, you can write and rewrite until the CD is full, and then the data becomes fixed. DLA-created media can be read only with newer CD-ROM drives and DVD-ROM drives that support multi-read mode.

A UDF reader might be required when using other computers to read unclosed DLA media. Install the provided UDF reader on other systems that need to read the disc, not on yours.

CD-R discs are playable on audio CD players. CD-RW discs are not playable on most audio CD players.

CD-RW media comes in three different types: normal, High Speed, and Ultra Speed. Normal media is usually designated 2X or 2X-4X. High Speed Media is often listed as 4X-10X or 4X-12X and bears the High Speed logo. Ultra Speed Media is usually listed as 16X-24X and bears the Ultra Speed logo. Your CD-RW can write to all three types of CD-RW media. If you use High Speed or Ultra Speed CD-RW media, computers with lower speed CD-RW drives cannot add data to this media. The following table shows the compatibility of different media in different drives, along with the logos that are on the drives and the media.
