Disadvantages of Compact Disk (CD)
- Inferior Capacity: CDs have more storage capacity than their predecessors, but subsequent storage mediums have more capacity. Storage capacity is lower than a hard drive or DVD, nowadays CD is not used at all.
- Older Technology: A compact disc’s limitation stems from its older read and write mechanism technology, which is based on 780nm wavelength.
- Inferior Quality: It should be noted that audio-video files with higher audio and video quality can be stored on DVDs and Blu-ray Discs.
- Durability Issues: Magnetic tapes are less durable than CDs. However, it is still fragile because it is easily scratched if not treated carefully. When exposed to severe heat and humidity, it might deform and become unusable.
- Obsolete Medium: Another issue of CDs is that they have become obsolete as better storage methods have become available.
- It’s also worth noting that compact discs aren’t suitable for backup storage because of their limited storage capacity, susceptibility to breakage, and obsolescence. It is preferable to use hard drives or solid-state drives.
