BD-ROM, also known as Blu-ray Disc Read-Only Memory, is an optical disc format that was developed by a group of 13 consumer electronics and PC companies, including Sony, Apple, and Panasonic. It is a high-resolution storage format that is part of the Blu-ray family and consists of pre-recorded data.
Blu-ray Disc (BD), invented and developed in 2005, is a digital optical disc data storage format designed to replace the DVD format. Blu-ray can store several hours of high-definition video (HDTV 720p and 1080p) and is commonly used for physical distribution of video games and feature films. It uses a blue laser (actually a violet laser) to read the disc, which allows for greater storage capacity compared to the wavelength red laser used for DVDs.
BD-ROM can only read audio and video data and can store up to 25 GB on a single-layer disc and 50 GB on a dual-layer disc. The format is the same size as a CD.
