Disc drives have become an essential part of modern-day computing. These devices come in different shapes and sizes and are used to read and write data from discs such as CDs, DVDs, and Blu-ray discs. Some other terms that are used to refer to disc drives include optical drives, CD-ROM drives, DVD drives, and BD-ROM drives. Optical drive is a more general term that encompasses all types of disc drives, while CD-ROM and DVD drives specifically refer to drives designed to read those respective disc formats. BD-ROM drives, on the other hand, are disc drives that are specifically designed to read Blu-ray discs. Despite the differences in terminology, all disc drives have one common goal, that is to access and extract data from optical discs.
