Ideal phase change recording layer for dual layer
Maxell's dual layer recording and even higher recording density technology realized a large recording capacity of 50GB, twice the storage capacity of current single layer disc (23.3GB). In addition, by introducing new phase change recording material and recording layer structure which enabled to maintain uniformed thickness of middle recording layer, Maxell achieved to obtain wider recording power margin and rewriting durability with low error rate even after 1,000 times recording. Also highly accurate spin coating technology contributed to cover layer with smooth surface and outstanding uniformity in thickness, offers stable and reliable performance in recording and playback.

Highly durable hard coating technology
For high density recording, dust and scratches can cause serious problems on accurate recording and playback. Maxell's highly durable hard coating technology solved these problems by providing static electricity discharge effect and avoiding dust, and protect discs from scratches on recording surface. |
 |
Sealed cartridge to guard disc
Highly precise molding technology makes it possible to provide extremely durable, dustproof sealed cartridge, together with hard coating technology, protect saved data from dust and scratches. |
 |
Better visibility of disc cartridge
By introducing red cartridge, it makes easier to identify dual layer cartridge from single layer (blue cartridge). Also semi-transparent hard case and index card corresponding to the cartridge colors are introduced for better and easier handling on filming and editing scenes. |
