JVC co-develops CD copy control technology

A new, encryption-based CD-ROM copy-protection technology is being developed by Japanese companies Hudson Soft Co. Ltd. and Victor Co. of Japan Ltd. (better known as JVC).

Dubbed "Root," the system relies on a software key built into CD-ROMs as they are pressed. Illegally-copied discs will lack the key, thwarting them from being used, according to the companies.

Earlier encryption technologies have often proved quickly crackable, but JVC and Hudson Soft say Root's difference is that its encryption key remains hidden and inaccessible during normal playback, unlike the keys of other protection systems.

JVC and Hudson Soft say they will use the technology to solicit CD-ROM pressing orders from American and Japanese software manufacturers.

Brother QL-820NWB Professional Label Printer

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
