The depicted rate is well within a healthy range. An individual error does not cause data loss yet, but a higher rate means the error correction mechanism is more strained, which can predict a possible age-related future data loss. Some optical drives support measuring the error rate in the error correction code. Over the last ten years, laptop computers no longer come with optical disc drives in order to reduce costs and make devices lighter, requiring consumers to purchase external optical drives. Read-only DVD and Blu-ray drives are also manufactured, but are less commonly found in the consumer market and mainly limited to media devices such as game consoles and disc media players. Compact discs, DVDs, and Blu-ray discs are common types of optical media which can be read and recorded by such drives.Īs of 2021, most of the optical disc drives on the market are DVD-ROM drives and BD-ROM drives which read and record from those formats, along with having backward compatibility with CD, CD-R and CD-ROM discs compact disc drives are no longer manufactured outside of audio devices. Some drives can only read from certain discs, but recent drives can both read and record, also called burners or writers (since they physically burn the organic dye on write-once CD-R, DVD-R and BD-R LTH discs). In computing, an optical disc drive is a disc drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs.
