CD Recordable
(PMD CDR 80, Sony CDQ 80): Blank CDR with capacity of 700mb. Once written to, the information cannot
be deleted or re-written.
Information can be written at 52x normal speed – i.e. if you are
recording a 3 minute song, it will record to CD in about 3.5 seconds.
CDR Recordable Rewritable
(Sony CDQ-RW74, Sony CDQ-RW
80): If information needs to be
deleted or re-written, the customer should use a CDR-W (rewritable). Because of the re-writing process, information
transfer is slower, therefore can only be written at 4x normal speed.
DVD Recordable
Due to the
proliferation of DVD and the availability of DVD drives / recorders, there are
now several slightly differing formats of blank DVD media on the market. If a customer is in any doubt as to the
product they require for their hardware, they should visit the following URL’s:
-
DVD-R
This is the most common format of
DVD media that we sell. It is
designed for virtually all PC and Mac based systems. It is a record-once format (like CDR) with a capacity of
4.7GB per disk. Information can be
written at 4x normal speed (i.e. a 1 hour piece will write in approximately 15
minutes)
DVD-RW:
Specification as above, but
re-writable. Please note that not
all PC / Mac based systems will accept re-writable media, so it is important
for the customer to check compatibility at the above links. Due to re-writing, transfer is 2.4x
normal speed.
DVD+R:
This product is designed for
stand-alone DVD drives mainly for the consumer / home market. The 2 most common drive manufacturers
for this media are Philips and Sony, although others are available. Data storage capacity is 4.7GB, which
equates to approximately 2 hours of video footage. Some drives are able to compress data to allow up to 4 hours
of recording.
DVD+RW:
Specification as above (DVD+R),
but re-writable.
