The new single-sided 25GB discs are single layer, whereas the 50GB products have a dual layer recording material structure.
TDK has begun shipping 25GB recordable and rewritable Blu-ray Disc media to retailers nationwide.
The single-sided discs are bare, cartridge-free media. The 25GB products are single layer whereas the 50GB products have a dual layer recording material structure.
Blu-ray Discs were originally released in Japan in April of 2003 with a protective cartridge. The cartridge was necessary in order to protect the recording material, which is manufactured close to the Blu-ray Disc's surface in order to realize the disc's high density recording capabilities.
TDK said it pioneered hard coating technology, eliminating the need for the cartridges. Every TDK Blu-ray Disc includes Durabis, a protective hard coating formulation that protects the disc and rapidly discharges static.
Retail pricing is set at $19.99 for a 25GB BD-R (recordable) $24.99 for a 25GB BD-RE (rewritable).
