FAQs On Optical Storage Systems
Q.1: What is storage capacity of optical storage device?
Answer:
A double-sided DVD can hold up to 700GB of data, whereas a CD-ROM has a maximum storage capacity of 650MB. For example, the smallest PMP format optical disc size is 2.5GB whereas double-sided and single layer.
Q.2: Can you retrieve data from an optical disc?
Answer:
If an optical disc is not too badly damaged, the data on it can typically be retrieved. Even when the data is being read from the disc, there are several circumstances where it might not be entirely recoverable or usable.
Q.3: Why laser beam is important to optical storage device?
Answer:
Without a laser beam, optical storage devices are nothing. Data is read from an optical disc using a laser. The laser beam is important for optical storage device to read and write the data. Laser beam produced by the laser source.
Optical Storage Systems
THe Optical memory is an electronic storage medium that uses a laser beam to store and retrieve digital (binary) data. In optical storage technology, a laser beam encodes digital data on an optical disc or laser disc in the form of tiny pits arranged in a spiral pattern on the surface of the disc. Digital Versatile Disk (DVD), Compact Disk (CD) and Blu-Ray Disk are the examples of optical storage device.
