Writable CDs and compatibility

The drive can write to CD-R and CD-RW discs, when used with writing 
software.
To play back (read) these CD-R and CD-RW discs on other CD-ROM drives, 
make settings on the writing software according to the purpose of the data.

CD-R Discs

Data can be written to this type of disc only once, and once it has been written, 
it cannot be erased. Music CDs created on CD-R disc media can be played on 
standard CD players.

CD-RW Discs

Data can be written to and erased from this type of disc repeatedly. Typically, 
a new CD-RW disc can be rewritten about 1,000 times.

unless it is designed to be CD-RW compatible.

High Speed CD-RW Discs

The drive can write to High Speed CD-RW disc media. Data written on High 
Speed CD-RW discs can be read by standard CD-ROM drives.

CD-RW discs. When writing or adding to such discs with a drive other than this one, make 
sure that the drive has the High Speed CD-RW logo. Also, always set the writing speed to 
that specified for the particular High Speed CD-RW disc media being used.

Ultra Speed CD-RW Discs

The drive can write to High Speed CD-RW and Ultra Speed CD-RW disc 
media. Data written to these discs can be read by standard CD-ROM drives.

Note

Drives that do not have the Ultra Speed CD-RW logo cannot be used to write to Ultra Speed 
CD-RW discs. When writing or adding to such discs with a drive other than this one, make 
sure that the drive has the Ultra Speed CD-RW logo. Also, always set the writing speed to 
that specified for the particular Ultra Speed CD-RW disc media being used.

When writing to CD-R and CD-RW discs, set the writing speed to that 
specified on the disc. Change the writing speed on the writing software.

About playback/reading compatibility in CDs

CD-R and CD-RW discs created with the drive can be read on most CD-ROM 
drives. However, some older CD-ROM drives cannot read CD-RW discs. 
In addition, CD-R music discs created and finalized with the drive can be 
played on most CD players, however, there are some CD players and 
automobile CD players that do not guarantee playback of CD-R discs.
Also, CD-R music discs created with the drive can be played back on many 
standard CD players. However, depending on the type of your player, playback 
of CD-R and CD-RW discs may not be supported.
