record your images on CDs and free your hard drive space for other uses.
Backup and Archive: Save critical information in the least expensive way. For just
pennies per megabyte, you can copy files to CD-ReWritable media or archive valuable
information for future reference. CDs are recognized as the most reliable, long-lasting
medium to store data. Plus, unlike other media used for backup or archiving, the information
stored on a CD is instantly accessible.
Distribute and Transfer Data: Send multimedia presentations and catalogs with high-
resolution images and CD-quality sound to anyone. With Yamaha CD-ReWritable drives,
you do not have to worry about media compatibility. Any ordinary CD-ROM drive can read
the data you store on a CD-R media using a CD-ReWritable drive.
1.2.3) CD-ReWritable Drives vs. CD-Recordable Drives
All Yamaha CD-RW drives are "multi-function" or "3-in-1" drives. This means that your new
drive may be used as a CD-R drive (to write once on CD-R media), a CD-RW drive
(to rewrite up to 999 times on CD-RW media), or as a CD-ROM drive (to play audio or
computer CDs).
1.2.4) How CD-RW Drives Write and Re-Write
To write on CD-R media, CD-RW drives write data by burning tiny pits into a green, gold,
or blue dye layer. The disc is read by a head which is simply looking for the absence or
presence of reflected laser light.
To re-write on CD-RW media, CD-RW drives write data by altering the alignment of crys-
talline structures in the media. When the disc is read by a laser, these changes in the
crystalline structure alter the phase of the effected light. The disc can be "wiped clean"
in an erase process that realigns the crystalline elements.
Your new Yamaha 3-in-1 CD-RW drive automatically recognizes and accommodates whatever
CD media is inserted. For better clarification, please study the table below:
