CES 2007 TDK today demo'd what it's calling 'Mini Blu-ray Discs' - single-layer recordable and re-writeable discs that are 8cm in diameter and capable of holding 16.5GB of data. The company also launched inkjet-printable standard-size BD-R media.

The smaller discs are prototypes - they have yet to be approved by the Blu-ray Disc Alliance, the next-generation optical disc format's governing body - designed to show the kind of product TDK has in mind for Blu-ray camcorders, the firm said.

TDK also showed off its prototype 200GB, a product it's been boasting about since April 2006, when it first announced it was working on such a disc. Less than a month later it said it had actually produced one.

Meanwhile, the printable 50GB recordable discs are due to ship in Q2 and should work with thermal and inkjet printers already capable of fixing images to 12cm discs. ®
