When the optical disc drive was first developed, it was not easy to add to computer systems. Some computers such as the IBM PS/2 were standardizing on the 3 + 1 ⁄ 2 -inch floppy and 3 + 1 ⁄ 2 -inch hard disk and did not include a place for a large internal device.
An older example of optical storage that does not require the use of computers, is microform. There are other means of optically storing data and new methods are in development. An optical disc drive is a device in a computer that can read CD-ROMs or other optical discs, such as DVDs and Blu-ray discs.
Optical drives let your computer read and interact with discs like CDs, DVDs, and Blu-rays. However, they're quickly becoming outdated.
In the 1964 removable disk media was introduced by the IBM 2310 disk drive with its 2315 cartridge used in IBM 1800 and IBM 1130 computers. [7] Magnetic disk media is today not removable; however disk devices and media such as optical disc drives and optical discs are available both as internal storage and external storage. [8]
Disk storage (also sometimes called drive storage) is a data storage mechanism based on a rotating disk. The recording employs various electronic, magnetic, optical, or mechanical changes to the disk's surface layer. A disk drive is a device implementing such a storage mechanism.
Internal SuperDrive floppy drive on a Macintosh LC II. The term was first used by Apple Computer in 1988 to refer to their 1.44 MB 3.5 inch floppy drive.This replaced the older 800 KB floppy drive that had been standard in the Macintosh up to then, but remained compatible [citation needed] in that it could continue to read and write both 800 KB (double-sided) and 400 KB (single-sided) floppy ...
However, not all optical drives provide this capability, and support for this feature can vary significantly between manufacturers and drive models. On drives lacking raw data access, users may rely on a less precise method: monitoring unexpected reductions in read speed, though this is a far less reliable indicator of disc health.
In the history of optical storage media there have been and there are different optical disc formats with different data writing/reading speeds.. Original CD-ROM drives could read data at about 150 kB/s, 1× constant angular velocity (CAV), [1] the same speed of compact disc players without buffering.
