The drive is a super-combination drive that integrates DVD+RW/+R and CD-RW
capabilities. Capitalizing on Ricoh's expertise accumulated with existing CD-RW and
DVD-ROM combination drives, we have developed some new mechanisms to achieve
incorporation of DVD+RW rewrite capabilities.
●
DVD writing has been made possible by tuning up a two-LD (laser diode) one-lens
pick-up that has one laser diode for CD and another for DVD.
●
With our analog front-end processor LSI for controlling pick-up, seek, and servo
mechanisms, as well as our digital controller LSI for controlling encoding/decoding,
both of which are newly developed, 2.4x-speed DVD writing which requires even more
precise control has been achieved.
●
The "radial-tilt correction mechanism" incorporated in the drive senses the disc
warpage and inclination and thereby corrects the laser angle so that the laser is always
directed toward the disc surface at the right angle. (It functions only when writing to or
playing DVD.)
●
A high-precision stepping motor is incorporated. This enables precise seeking even on
DVD+RW/+R with a narrow track pitch, and achieved reduction of operating noise
●
As a CD-RW drive, it provide the performance of 12x CD-R write, 10x CD-RW rewrite,
and 32x CD-ROM/R/RW read speeds.
●
As a DVD-ROM drive, it provides a performance of 8x read speed.●
JustLink

has made auto-avoidance against buffer underrun
errors possible.
●
An improved anti-heat design means that no cooling fan is needed.●
Easy-to-use tray model.●
Enhanced-IDE (ATAPI) model●
Compliant with industry standard Orange Book Part II (CD-R) and Part III (CD-RW).●
Can read not only CD-R and CD-RW discs, but also video CDs, music CDs, photo

, and CD-Text
●
The recorded CD-RW media can be played in a DVD player or a multi-read CD-ROM
Player, maintaining future compatibility.
