Answer :
Final answer:
A DVD-R DL actually stores nearly double the data of a standard DVD, not less. The real disadvantages are higher cost, compatibility issues, and slower recording speed due to increased capacity. These discs use laser light to read data encoded in pits and bumps in a spiral track.
Explanation:
The assertion that a DVD-R DL (dual layer) disc stores less data than an ordinary DVD is incorrect. In fact, one of the primary differences is that a DVD-R DL can store nearly double the amount of a single-layer DVD. A standard single-layer DVD can typically hold about 4.7 gigabytes (GB) of data, whereas a dual-layer DVD-R DL provides approximately 8.5 GB of data storage. This increased capacity is due to the second physical layer within the disc which can be read by the laser.
However, there are certainly disadvantages to using a DVD-R DL. For example, DVD-R DL discs can be more expensive, have compatibility issues with some DVD players, and the recording process can be slower due to the larger storage capacity and the need for the laser to refocus to read or write to the second layer.
The information on these optical discs, whether CD, DVD, or Blu-Ray, is encoded digitally using tiny pits and bumps arranged in a spiral track. These physical data representations are read by lasers; a DVD player uses red laser light, whereas a Blu-Ray player employs blue laser with a shorter wavelength, which is suitable for reading higher density data storage.
