How much data can you fit on a Blu-ray disc?
A single-layer disc can hold 25GB. A dual-layer disc can hold 50GB.To ensure that the Blu-Ray Disc format is easily extendable (future-proof) it also includes support for multi-layer discs, which should allow the storage capacity to be increased to 100GB-200GB (25GB per layer) in the future simply by adding more layers to the discs. Over 9 hours of high-definition (HD) video can be stored on a 50GB disc. About 23 hours of standard-definition (SD) video can fit on a 50GB disc. What is the BD-R/RE AV format?BD-R/RE Audio Visual (BD-R/RE AV) is a format designed to record and play back full quality high (HD) and standard (SD) definition digital television broadcasts on BD-R (recordable) and BD-RE (rewritable). The BD-AV will allow consumers for example to use HD (or SD) video content in order to “author” a BD disc that will be playable in a standalone BD-player. SD material can be captured from analog sources and direct transfers from DV camcorders, allowing up to 2 hours of HD material t

How fast can you read/write data on a Blu-ray disc? According to the Blu-ray Disc specification, 1x speed is defined as 36Mbps. However, as BD-ROM movies will require a 54Mbps data transfer rate the minimum speed we’re expecting to see is 2x (72Mbps). Blu-ray also has the potential for much higher speeds, as a result of the larger numerical aperture (NA) adopted by Blu-ray Disc. The large NA value effectively means that Blu-ray will require less recording power and lower disc rotation spee
