The disc, called VR-100BR1, is a triple-layer single-write Blu-ray disc which conforms with the BDXL format specifications defined by the Blu-ray Disc Association for high-capacity Blu-ray discs.
Current Blu-ray discs can store up to 50GB of data, so this latest product from Sharp doubles current capacity to allow recording of up to 12 hours of terrestrial digital TV.
The new discs also include a "hard coat" protective coating, which helps protect from scratches, dirt and fingerprints, which may damage the disc and lead to errors.
Other companies have been working on developing 100GB Blu-ray discs for some time, with Sony even developing an eight-layer 200GB disc, but none of them have managed to actually get them into production. Now that Sharp has started the ball rolling, however, we hope to see others joining in.
Sharp has not revealed pricing, but rumours suggest a hefty price tag of $60 (£40) which could drop as other companies develop the technology and help drive prices down.
The new discs will be in available in Japan from July 30 with an international release date yet to be decided.
