Blu-ray LTH Type Discs

Blu-ray MediaHawksM20 November 2009

Blu-ray, also known as Blu-ray Disc (BD) is the next-generation optical disc format developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The applications for Blu-ray span the entire storage spectrum–Data, Audio, Photo and Video storage for personal and professional use.

Verbatim BD-R LTH Type Technology BD-R LTH Type discs offer a more affordable solution to high-definition video storage. In comparison to standard BD-R discs which use inorganic dye, BD-R LTH discs use an organic AZO layer which MKM developed leveraging its many years of success in developing organic AZO recording layers for CD-R and DVD-R media. BD-R LTH Type media is applied using the same dye spin coating process as CD-R or DVD-R media.

Recorded data lies close to the surface of BD discs. Therefore all Verbatim BD media features a proprietary Hard Coat finish. This layer provides added protection from scratches, dust particles and fingerprints that can damage data and cause recording and playback errors.

  • Store up to 25GBs of information on BD-R LTH Type discs
  • BD-R LTH discs can record at speeds up to 2X
  • Increased sensitivity to laser light – Key requirement for optimized recording performance
  • Controls heat interference between consecutive recorded marks – Less jitter and reduced degradation of recording marks
  • Wide power margin – Excellent recording compatibility and prolonged archival life

BD-R LTH Type Recorder Compatibility With increased availability of recorders, players and camcorders that support this new technology, the demand for BD-R LTH is high. The following BD disc recorders (Format v1.2 standard) are compatible with the latest LTH Type BD Recordable discs*, as of November 2009:
