What is a type of disk on which a laser has digitally recorded information such as audio video or computer data?

A type of disk on which a laser has digitally recorded information is called a CD (Compact Disc) or DVD (Digital Versatile Disc). These optical discs use laser technology to read and write data, allowing them to store audio, video, and computer files. CDs typically hold up to 700 MB of data, while DVDs can store about 4.7 GB to 8.5 GB, depending on the format. Blu-ray discs are another type, offering even higher storage capacities for high-definition video and data.
