Optical Storage

Optical Storage Systems

We have been supplying optical storage for the past 20 years to provide data protection for information which needs to be retained or archived for many years.

Optical storage relies on a laser to write data on an optical disc, these can be CD, DVD, MO, UDO or Blu-ray. Data stored on an optical disc is typically a critical backup or archive data that needs to be kept for a very long time. Optical storage has massive benefits over current storage technologies.

  1. Optical discs written in ISO9660, UDF can be read by any compatible drive as it is written in an open standard
  2. Does not require any special software to read discs
  3. Does not require any special storage requirements
  4. Optical discs are very robust
  5. Have an archive life of 50+ years

We are able to supply the two most common Optical Technologies currently available these are:

  • Blu-ray
  • UDO (Ultra Density Optical)

Optical Storage Overview

For over 25 years optical has been used to archive long term critical data from medical records, emails, scanned documents, legal documents, X-rays for non medical purposes, including patent and design information.

Blu-ray Optical Disc Capacity

The current Blu-ray disc capacity is 125GB using a four layer disc and called BDXL.  Whilst 125GB might not seem a large amount of storage compared to hard disks, it is more than enough to store a 4k movie or store 1.25 million scanned A4 documents.

Technical Overview

There are two methods for writing optical storage both change the physical properties of a an optical disc via magnetism or etching pits into the disk surface.

  1. One way to write an optical disc relies on a Red (CD/DVD) or Blue (Blu-ray/UDO) laser to write data
  2. Older optical storage technologies (Magneto Optical, DVD-RAM) relied on a laser to heat the disc surface and change the magnetic properties on the optical disc
