In spite of having the "Blu-ray" brand, "BDXL" (or "BD-XL") is separate from the original "BD" format, meaning existing Blu-ray drives that predate the release of BDXL (mid-2010) do not support BDXL. Even Blu-ray drives released after that date may not necessarily support BDXL unless explicitly stated. [9]
ImgBurn is an optical disc authoring program that allows the recording of many types of CD, DVD and Blu-ray images to recordable media (.cue files are supported as of version 2.4.0.0). [3] Starting with version 2.0.0.0, ImgBurn can also burn files and data directly to CD or DVD. It is written in C++.
Such media must be played in specially tuned drives, since the phase-change material has less of a contrast in reflectivity than dye-based media; while most modern drives support such media, many older CD drives cannot recognize the narrower threshold and cannot read such discs. Phase-change discs are designated with RW (ReWriteable) or RE ...
The Blu-ray Disc Association recommends but does not require that Blu-ray Disc drives be capable of reading standard DVDs and CDs, for backward compatibility. [236] Most Blu-ray Disc players are capable of reading both CDs and DVDs; however, a few of the early Blu-ray Disc players released in 2006, such as the Sony BDP-S1 , could play DVDs but ...

[28] Blu-ray eventually prevailed in a high definition optical disc format war over a competing format, the HD DVD. A standard Blu-ray disc can hold about 25 GB of data, a DVD about 4.7 GB ...
BD-RE represents a Blu-ray disc which can be read or written many times. In addition some of these media support MultiLevel Recording formats, for example dual layer (written as "DL"), and DVD also supports a "RAM" version (similar to RW), although this is not widely used in the popular consumer market.
BD-J, or Blu-ray Disc Java, is a specification supporting Java ME (specifically the Personal Basis Profile of the Connected Device Configuration or CDC) Xlets for advanced content on Blu-ray Disc and the Packaged Media profile of Globally Executable MHP (GEM).
AACS uses cryptography to control and restrict the use of digital media. It encrypts content under one or more title keys using the Advanced Encryption Standard (AES). Title keys are decrypted using a media key (encoded in a Media Key Block) and the Volume ID of the media (e.g., a physical serial number embedded on a pre-recorded disc).
