While most Taiwanese media manufacturers have been reluctant to mass produce Blu-ray Discs, Ritek has begun to invest heavily in the format. According to the Taiwan Economic News, the company is already the world's third largest Blu-ray Disc manufacturer. Along with recordable media, Ritek manufactures pre-recorded discs through its subsidiary, U-Tech Media Corp.
Ritek has climbed to the world`s No. 3 BD disc maker in this year from No. 4 in 2007. The Taiwan company is scheduled to install three new BD disc production lines to meet such growing demand. The company stressed that it has a very flexible production system so could expand capacity easily to meet changing market conditions.

Ritek and its subsidiary U-Tech Media Corp., a maker of pre-recorded media, jointly announced the Rambo IV BD disc, which will be shipped from August. The BD disc is the first pre-recorded BD disc (double-layer) with storage capacity of 50 Giga-byte (GB).
