The Sony BD-R Blu-ray Recordable Disc is a write-once, single layer disc. Single-layer Blu-ray discs record 25GB of data, which is equivalent to 5+ standard DVDs. The Blu-ray format is heavily supported by Hollywood's movie studios, and eventually as the DVD format is superseded it will be the default disc format for the release of films. Beyond the muscle of the studios behind it, the Blu-ray format delivers higher resolution video and better sound, and all Blu-ray discs have a hard external coating that is extremely resistant to scratches which would affect the access of the recorded information. These particular Sony Blu-ray discs (a spindled package of 50) have a top surface which is optimized for printing with inkjet and hub printers.
