Are there’re writable optical disks?

Recordable and writable optical discs Formats such as CD-R and DVD-R are “Write once read many” or write-once, while CD-RW and DVD-RW are rewritable, more like a magnetic recording hard disk drive (HDD).

What are the 3 types of optical media?

There are three main types of optical media: CD, DVD, and Blu-ray disc. CDs can store up to 700 MB (megabytes) of data, and DVDs can store up to 8.4 GB (gigabytes) of data. Blu-ray discs, which are the newest type of optical media, can store up to 50 GB of data.

What are the examples of optical disc?

Most of today’s optical disks are available in three formats: compact disks (CDs), digital versatile disks (DVDs) — also referred to as digital video disks — and Blu-ray disks, which provide the highest capacities and data transfer rates of the three.

Which optical disk is writable?

CD-RW(CD-Rewritable) discs can be written to repeatedly, by deleting or overwriting old data to make room for new data. CD-RW discs can be rewritten up to 1,000 times.

How many types of optical disks are there?

Six categories of optical media are available to meet most storage requirements: CD-ROM, DVD-ROM, DVD-RAM, recordable media, write-once read-many (WORM) optical cartridges, and erasable optical cartridges.

Which of the following is used by an optical disk to read and write data?

laser beam
An optical disk drive uses a laser beam to read the data from the disk as it is spinning. It distinguishes between the pits and lands based on how the light reflects off the recording material. The drive uses the differences in reflectivity to determine the 0 and 1 bits that represent the data.

Which of the following is not the type of optical disk?

The correct answer is option 2 i.e Magnetic tape. Magnetic tape: It was developed in Germany in 1928, based on magnetic wire recording. It is a medium for magnetic recording, made of a thin, magnetizable coating on a long, narrow strip of plastic film.
