Optical drives for computers come in two main form factors: half-height (also known as desktop drive) and slim type (used in laptop computers and compact desktop computers). They exist as both internal and external variants. Half-height optical drives are around 4 centimetres tall, while slim type optical drives are around 1 cm tall.
MS-DOS/PC DOS versions 4.0 and earlier assign letters to all of the floppy drives before considering hard drives, so a system with four floppy drives would call the first hard drive E:. Starting with DOS 5.0, the system ensures that drive C: is always a hard disk, even if the system has more than two physical floppy drives.
Drive mapping is how MS-DOS and Microsoft Windows associate a local drive letter (A-Z) with a shared storage area to another computer (often referred as a File Server) over a network. After a drive has been mapped , a software application on a client 's computer can read and write files from the shared storage area by accessing that drive, just ...
The host computer may run Microsoft Windows, but with some possible shortcomings: to read a Mac's HFS-formatted partitions, extra drivers such as MacDrive, TransMac, MacDisk, or HFSExplorer are necessary. Users also must ensure their computer possesses appropriate interface hardware in order to physically connect to a Mac in Target Mode.
Many operating systems like the classic Mac OS (from Mac OS 8.6 up), macOS, Linux, and Microsoft Windows XP can use DVD-RAM directly, while earlier versions of Windows require separate device drivers or the program InCD. Windows XP can only write directly to FAT32 formatted DVD-RAM discs.
A magneto-optical drive is a kind of optical disc drive capable of writing and rewriting data upon a magneto-optical disc. 130 mm (5.25 in) and 90 mm (3.5 in) discs are the most common sizes. In 1983, just a year after the introduction of the compact disc , Kees Schouhamer Immink and Joseph Braat presented the first experiments with erasable ...
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 storage differs from other data storage techniques that make use of other technologies such as magnetism, such as floppy disks and hard disks, or semiconductors, such as flash memory.
Optical discs are not prone to uncontrollable catastrophic failures such as head crashes, power surges, or exposure to water like hard disk drives and flash storage, since optical drives' storage controllers are not tied to optical discs themselves like with hard disk drives and flash memory controllers, and a disc is usually recoverable from a ...
