We read
the announcement last week that NEC successfully created this drive, now thanks
to PhysOrg we can take a look at it!

This compatible head technology was developed by using
three lasers, the blue, red and infrared laser diodes ("LD"), as the light
source, thus enabling optimal reading of each disc through the optical
head using a single objective lens.
- Correction of the difference in
substrate thickness and wavelength, which causes spherical aberration, was
corrected by changing the magnification of the objective lens. Control of
the numerical aperture of the objective lens corresponding to each disc
format is enabled by an aperture control element that features wavelength
selectivity, which realizes stable
reading. |

this very interesting piece of hardware.

Would be nice to get 13GB of unchanged miniDV footage onto one cheap disc (finally). Two or more tapes on one disc would be even nicer. A lot depends on price and availability.
Right now all they're talking about is ultra-boring playback formats, like the world revolves around Hollywood. More focus on computer users (ie. common Joe) with real, everyday data archival needs would be nice. Blu-Ray certainly sounds better (on paper) for those tasks.
All it needs are some flashing LEDs and it would look perfect hanging from the Christmas tree!
