Which type of disks are considered optical?

Optical disks are a type of storage medium that uses lasers to read and write data. CDs (Compact Discs) and DVDs (Digital Versatile Discs) fit this definition because they are manufactured with a reflective surface and are read by a laser in an optical drive. The data is encoded in the form of tiny pits and lands on the surface of the disc, which the laser interprets as binary data. In contrast, floppy disks, USB drives, and hard drives utilize magnetic or flash memory technologies rather than optical methods. Floppy disks rely on magnetic storage, while USB drives use flash memory, which does not involve lasers or light to access data. Hard drives, similarly, use magnetic plates to store data, further distinguishing them from optical disks. Thus, the identification of CDs and DVDs as optical mediums is based on their unique laser-based data retrieval and writing capabilities.
