The smaller pits, smaller beam and shorter track pitch together enable a single-layer Blu-ray disc to hold more than 25 GB of information — about five times the amount of information that can be stored on a DVD. As the optical disk spins, a laser beam is used to detect these irregularities on the disk’s reflective surface. CD-ROM CD-ROM stands for Compact Disk-Read Only Memory. There are three basic types of optical disks: CD-ROM :Like audio CDs, CD-ROMs come with data already encoded onto them. Blu-ray disc – A digital optical storage device which was intended to replace the DVD format. Question: Where Is The Tallest Building In China?

Optical Storage Devices - Other Optical Storage Devices •A CD-Recordable (CD-R) drive lets you record your own CDs, but data cannot be overwritten once it is recorded to the disk. Hardware components that read/write to storage media are called storage devices. DVD-ROM There are four types of optical disks- CD-ROM- Compact Disk Read Only Memory WORM – Write Once Read Many Erasable Optical Disk DVD ROM. However, the actual speeds depend on the type of data being written to the disc. Initially, many of these drives were read-only, meaning they could only access data on already created disks and couldn’t write new content to existing or blank disks. Magnetic tape. CDs are created to store the audio files in the earlier days and store 700MB. 1.CD-ROM, 2. It uses flash memory to store data, which provides better performance and reliability over an HDD.
