When was Blu-ray Disc
introduced?
The Blu-ray Disc specification was
officially announced in February 2002. Blu-ray
Disc recorders were first launched in Japan in
2003. Blu-ray Disc players appeared globally in
early 2006.
What does the name Blu-ray Disc mean?
The name Blu-ray Disc refers to the blue laser
that is used to read from and record to a Blu-ray
Disc. In comparison to a red laser, as used in
DVD and CD, a blue laser allows for a much
higher density and hence larger storage
capacity. "Blu" is intentionally spelled without
an "e" to allow for a distinctive registration
of the trademark name.
What is the correct abbreviation of Blu-ray
Disc?
Blu-ray Disc can be shortened down to "BD".
When was the Blu-ray Disc Association
established?
The group of companies that develops the Blu-ray
Disc format was initially called Blu-ray Disc
Founders, and it was established in early 2002.
In June 2004, the group was renamed to Blu-ray
Disc Association to underline its intentions to
welcome other companies to join the association.
What companies support Blu-ray Disc?
Virtually all major consumer electronics
companies plus the world's leading PC and blank
media manufacturers support the Blu-ray Disc
format. Currently, there are over 150 member
companies.
What is the maximum storage capacity & speed
for a Blu-ray disc?
Maximum capacity for a single layer Blu-ray disc
is 25GB. The maximum recording speed in case of
Blu-ray discs is 6x. In case of certain drives,
an over burn support of 8x speed is also
feasible.
Blu-ray Disc for Video
What is the quality of Blu-ray Disc video?
Blu-ray Disc offers HDTV video quality that far
surpasses any other medium or broadcast format
available today. With High Definition video with
a resolution of up to 1920x1080 and up to a 54
Mbit/sec bandwidth (roughly double that of a
normal HDTV broadcast), no other format can
match Blu-ray Disc's video quality. Furthermore,
due to the overwhelming capacity of a Blu-ray
Disc, no tight compression algorithms that may
alter the picture quality are required, as with
other formats that offer less recording space.
Depending on the application, Blu-ray Disc also
supports other video formats, including standard
definition TV.
How much video will fit on a Blu-ray Disc?
This depends on the decisions on the usage of
video bandwidth, the number of audio tracks and
other criteria made by the author of the disc.
Furthermore, the choice of the used codec also
influences playback time. On average, a
single-layer disc can hold a High Definition
feature of 135 minutes using MPEG-2, with
additional room for 2 hours of bonus material in
standard definition quality. A double-layer disc
even extends these numbers up to 3 hours in HD
quality and 9 hours of SD bonus material. Using
any of the advanced codecs, these numbers can
even be significantly increased.
Do I need an HDTV to use Blu-ray Disc?
In order to view a Blu-ray Disc, you need a TV
that is HD-Ready, that is: equipped with an HDMI
input port.
Blu-ray Disc for Data
How does the capacity of a Blu-ray Disc compare
to other media?
A Blu-ray Disc can hold up to 25 gigabytes of
data. This compares to about 5 recordable DVDs
(or 3 double-layer DVDs), or around 35
recordable CDs. As a result, Blu-ray Disc is the
ideal, cost-effective, removable storage medium
for the storage of large amounts of data and
video.
What kind of data can be stored on a Blu-ray
Disc?
Any form of data available on a PC can be stored
to a Blu-ray Disc, including text documents,
images, video and audio files. Using the
appropriate software or operating support, a Blu-ray
Disc can offer the functionality of a large
removable hard disk drive.
Can I record video to a Blu-ray Disc using a PC?
Yes. Using the appropriate software, you can
edit standard or High Definition video (for
example from a camcorder) and then record it to
a Blu-ray Disc. When recorded in the Blu-ray
Disc video format, the end result can be played
in a Blu-ray Disc player connected to a TV.
How can one keep data secure in the media for a
long period of time?
In order to maintain the integrity and security
of your data on discs, you just need to follow a
few basic `dos and don’ts’. These are:
Do’s
- Handle the disc only by its outer edge or the
hole in its center.
- Store discs upright (book style) in plastic
cases specified.
- Return disc to storage cases immediately after
use.
- Open a recordable disc package only when you
are ready to record data on that disc.
- Store discs in a clean, cool, dry and dark
environment.
- Remove dirt, foreign material, fingerprints
and liquids by wiping the data side of the disc
with a clean fabric in a straight line from the
center of the disc towards the outer edge.
Do Not
- Touch the surface of the disc.
- Bend the disc.
- Use adhesive labels.
- Store disc horizontally for a long time
(years).
- Expose disc to extreme heat or high humidity.
- Expose recordable disc to prolonged sunlight
or other source of ultraviolet light.
- Write or mark in the data area of the disc
(Area the laser `reads’).
How long will the data recorded on a BDR disc
remain readable?
Lifetime estimation of any storage medium is a
very complex and statistics -based process.
Improper testing or measurement procedures can
seriously impact and compromise lifetime
estimates. Moser Baer & OM&T have performed
extensive media longevity studies using these
industry defined tests and mathematical modeling
techniques, with results proving longevity well
in excess of 50 years. The caveat is how you
handle and store the media. With proper handling
and storage your BDR can be usable for as long
as you want.
Can I burn BDRs over the network?
The files and folders you want to burn should
ideally be copied to your local hard drive
before you burn them. It is never a good idea to
burn files directly over the network, as you
have no control over network traffic, and any
undue interference could ruin the burn process.
Also, if your source BDR has scratches on it,
then you should first copy the files to your
hard drive before burning. It is also advisable
to disable all external access to your machine
before you start burning.
My Blu-ray disc doesn’t record at the mentioned
speed?
The speed drop may be on account of hardware &
software compatibility. The following points
should be considered while using a Blu-ray disc:
- BD Drives require minimum Intel Pentium IV
2GHz processor, 1 GB of RAM, Windows XP SP2 or
latest, Microsoft DirectX9.0c (Oct 10th 2006) or
latest.
- Latest Nero recording software (Nero CD Speed
Version 4.9.0.0) is required and recording
should be done with Streaming option always ON.
I am facing problem in playing BDR/RE media
recorded with video files?
- The PC should have the Graphics Card – NVidia
GeForce 6600GT, 7600GT, 7950GTX, 8800 or newer.
- The PC should have – PCI-Express video card
with DVI/HDMI and HDCP-support, Display/TV with
HDMI input or GDCP-enabled DVI input.
My Drive refuses to recognize the media?
This could be on account of the following
reasons:
The Read Back time is too high on my Blu-ray
disc?
This could be on account of the following
reasons:
I am not able to record full data on the disc?
This could occur in case the disc outer surface
has a scratch. This requires proper handling of
the disc to avoid such problems in future.
Please refer to the question on “How can one
keep data secure in the media for a long period
of time?” for understanding more details on disc
handling & management.
