.
BD-R (Single or double layer)
Blu-ray Disc Recordable. A BD-R disc can be recorded once, and
cannot be accidentally erased. BD-R is the ideal format for archiving
valuable data or storing and distributing video material.
BD-RE (Single or double layer)
Blu-ray Disc Rewritable. A BD-RE disc can be recorded over and
over again (good quality Blu-ray discs can be overwritten approxi-
mately 10,000 times). It offers extensive editing functionality on the
disc. BD-RE is the ideal format for making sequential backups, or
recording video for time shifting purposes.
BD-ROM
Blu-ray Disc Read Only Memory. A BD-ROM disc contains pre-re-
corded data. Although a BD-ROM may contain any form of data,
most BD-ROM discs will contain movies in High Definition format,
for playback on Blu-ray Disc players.
BD-ROM can be read on your computer using the LaCie d2 Blu-ray
drive provided you own the appropriate playback software, compat-
ible system, graphic card and monitor.
BD-R LTH
BD-R LTH (“low-to-high”) is a write-once Blu-ray disc format that
supports less expensive Blu-ray discs with an organic dye recording
layer. The additional advantage of BD-R LTH is that many existing
Blu-ray burners are compatible with this new format and no further
investment in new technology is necessary.
