As compared to magnetic memory, opticalmemory is a relatively new secondary storage medium. It has provided to be a promising random medium for high-capacity secondary storage, as it can store large amounts of text of datain limited space. An optical-disk storagesystem consists of a rotating disk, which is coated. With a thin metal or any other mat...
Storage Capacity –It refers to the amount of data that can be stored in an optical storage system. It is directly proportional to the spot size and the geometrical dimensions of disk.Data Transfer Rate –It refers to the speed at which data can be read from the optical storage systems. It depends on the linear density and the rotational speed of the drive.Access Time –It refers to the time taken to access the desired data from the optical storage systems. It is directly proportional to the weight of head and rotation speed of the disk.Optical storage devices are commonly employed in data storage media. 1. In Computers:An optical diskcan be used by a computer to store vast amounts of data. The use of optical discs has the advantage of being less expensive than magnetic disks. An optical disc can hold more data than a hard disk. 2. In Audio Players:Every type of audio device, incl...
The cost-per-bit of storage for optical disks is very low.The use of a single spiral track optical disks an ideal storage medium for reading large blocks of sequential data such as music.Due to their compact size and light weight, optical disks are easy to handle, store, and port from one place to another.It is read-only (permanent) storage medium. Data once recorded, cannot be erased and hence, the optical disks cannot be reused.The data access speed for optical disks is slower than magnetic disks.It requires a more complicated drive mechanism than magnetic disks.Apr 16, 2014 · The article then explores the most common data formats for optical media: Compact Disc Digital Audio, ISO 9660, the Joliet and HFS extensions, and the Universal Data Format (with an eye towards DVD-Video).
