It works with either type of cable. The standard capacity of a DVD is 4.7 GB. The next type of optical disc that came on the market was the DVD. Two major types of secondary storage devices: 2. controllers, it is disk duplexing. 4. OPTICAL DISC TYPES Types of optical disc CD-ROMs/DVD-ROMs (read-only-memory) are commercial grade discs and use a metallic data layer. An optical disk is used to hold information for a permanent as well as a temporary basis. CD-R drive – Reads data from CD and can also write to CD . The speed of CD drive specifies the amount of data the CD drive reads from the CD calles as Transfer Speed . CD-ROM Drive CD-R Drive 3. 2. •DVD-ROM: • It is a Random access device; read/write head can be moved to any location on the platter Floppy Disk These are small removable disks that are plastic coated with magnetic recording material. Other issues relevant to the management or mainte-nance of optical systems are beyond the scope of this document. CD-ROM drive – Reads data from a CD. Excluded, for example, are such topics as care and maintenance of the disc drive device and associated hardware and software; digital With some CDs-R inserted into an optical drive, I see a CD-R ; With some DVDs-R inserted into an optical drive, I see a DVD-ROM is listed as disc type, instead of DVD-R since DVD-R is inserted onto the drive. Direct Access Storage Devices (DASDs) – Magnetic Discs Hard disks (high capacity, low cost, fast) Floppy disks (low capacity, lower cost, slow) – Optical Disks CD-ROM = (Compact disc, read-only memory 3. The optical disk is considered an integral part to store the output of the sophisticated invention called the computer. It is a storage device in which optical (light) energy is used. Intended initially for movies, they were quickly adopted in computer systems as well. This is because SPDIF is the encoding or data link protocol and not the wire or cable that runs it over. Optical Disks Magnetic Disk The Magnetic Disk is Flat, circular platter with metallic coating that is rotated beneath read/write heads. Optical disc drives use removable media to store and retrieve data, typically 5.25". and DVD structure, disc life expectancy, and conditions that affect optical discs. CD-RW Drive 6. CD-RW drive – Read , write and Rewrite. With some DVD-R inserted into an optical drive, I see a DVD-R is listed as disc type. The metal layer is then applied to the base, creating the data layer. It can be sent over coaxial or optical cables. You will find many types of optical disk which is useful in various terms and processes. Types of CD Drives : 1. Serial Devices – Magnetic tapes (very fast sequential access) It is a computer storage disk that stores data digitally and uses laser beams to read and write data. SPDIF is a format that interconnects components in home entertainment systems or home theaters with digital high-fidelity systems for sound and music. 7. The lands, or flat surfaces on the CD, are considered to be the "0" in binary code. This layer is created using a molding machine that stamps pits (depressions) and lands (flat surfaces) into a polycarbonate substrate base. Optical disk An optical disk is any computer disk that uses optical storage techniques and technology to read and write data. Types of optical discs include •CD-ROM: Data CDs can typically hold 700 MB, can read and write at up to 52x (7.8 MB/s), and can rewrite at up to 32x (4.8 MB/s).
