The drive ships in an OEM package.
The box contains:
- 16x CD-R and High Speed CD-RW (4x-10x) from Primedisc ;
- 4 screws and an Eject Stick
- Analog cable for connecting the drive to a sound card;
- IDE cable.
Character and method of recording:
In our lab we had a preproduction sample.
That is why there is neither a user manual nor software for CD recording.
Although the recorder had some software with it, it wasn't officially announced
when we received it, and NEC workers recorded on a CD-R an unreleased version
of the Nero Burning ROM - v22.214.171.124. This version was used in the tests.
The tests show that the drive doesn't like much our technological cyanine
CD-R discs with ATIP 4M. There was an error at the first minutes of recording
(note that these low-quality discs are recorded at 4x, which is the low
limit of the most of high-speed CD-RW drives).
Thus, instead of the cyanine disc we tried a CD-R from SKC in a bulk
package. But the recorder considered it too poor in quality as well for
recording at 24x and suggested the recording was implemented at 3 other
speeds with the highest being 16x.
The appearance is somewhat square and rectangular, though the most of manufacturers
today move toward roundish forms. However, such square forms create a NEC's
On the front panel you can find one LED which works in one-color mode,
a headphones jack, a mechanical volume control, an emergency ejection hole
and a rectangular tray button which produces a sharp click when pressed.
When going out the tray buzzes. The rear panel has a digital-out.
Ejected discs are quite warm. But the drive works rather quietly, without
