The four new products include the BD-R25 (single-sided, single-layer, 25GB) and BD-R50 (single-sided, dual-layer, 50GB) write-once type discs, as well as the BD-RE25 (single-sided, single-layer, 25GB) and BD-RE50 (single-sided, dual-layer, 50GB) rewritable discs.

Driven by the continuously expanding data storage requirements of todayâ€™s digital society, as well as the rapid emergence of high-definition broadcasting, demand has grown for discs that achieve larger capacities and higher-speed recording than previous formats. The BD-R and BD-RE products introduced by TDK are bare, cartridge-free discs that rise to the challenge by delivering larger capacities and high speed recording without requiring a cumbersome cartridge to ensure reliability.
