What is the latest write-once optical storage media?
A. Digital paper
B. Magneto-optical disk
C. WORM disk
D. CD-ROM disk
E. None of the above
Answer: Option C
Solution (By Examveda Team)
The correct answer is Option C: WORM disk.Let's break down why:
WORM stands for "Write Once Read Many".
This means you can write data to the disk once, and then read that data many times.
It's a type of optical storage where the data is permanently recorded.
Why not the other options?
Digital paper: This is still a developing technology and not a standard optical storage medium.
Magneto-optical disk: These are rewritable, not write-once.
CD-ROM disk: CD-ROMs are typically pre-recorded or mastered, and while they are read-only for the user after creation, the creation process itself is not "write-once" in the same way a WORM disk is. Furthermore, CD-ROM is an older technology.
None of the above: WORM is a valid write-once optical storage media.
Therefore, a WORM disk best fits the description of a latest write-once optical storage media.

Latest Write once optical storage media is M-Disc.
Digital paper is not the latest write-once optical storage media. Digital paper, also known as interactive paper, is a technology that uses a patterned paper and a digital pen to capture handwritten notes, not a storage medium itself. While it utilizes optical phenomena for capturing handwritten data, it is not a form of optical storage in the same way as CDs, DVDs, or Blu-ray discs. The latest write-once optical storage media are generally considered to be Blu-ray discs.
Here's why digital paper is not a write-once optical storage medium:
Function:
Digital paper is designed for capturing handwritten notes and transferring them to a digital format, not for storing large amounts of data long-term.
Mechanism:
It relies on the interaction between the patterned paper and a digital pen to track and record the pen's position.
Optical Storage:
True optical storage media, like CDs, DVDs, and Blu-ray discs, use lasers to read and write data in the form of pits and lands on the disc surface.
Write Once, Read Many (WORM):
While Blu-ray discs can be write-once (BD-R), meaning they can only be written to once and then read many times, digital paper doesn't fit this definition. Digital paper doesn't store data in the same way, and the digital pen simply captures the strokes, not the actual data being stored on the paper itself.
