What is BLU-RAY DISK?
In
the world of HARDDISK, SSD and cloud storage, CDs, DVDs, BLU-RAYs, and even
PENDRIVE or MEMORY CARDs that were created several years ago are almost out of
date. All these STORAGE DEVICEs were quite advanced in their own time. But as time
progresses, the demand for people has increased, and the importance of these
STORAGE DEVICEs has gradually diminished.

If we go back about
20 years today, at that time, COMPUTER had only FLOPPY DISK as a PORTABLE
STORAGE DEVICE. Which could STORE DATA at only 1.5 MEGA-BYTE.
After that, CD or COMPACT DISK came into the market to stir up worldwide. Which
could STORE DATA up to 700 MEGABYTE. After that, the DVD and
BLU-RAY DISK are slowly coming to market. There are two parts to this DVD and
BLU-RAY DISK. SINGLE LAYER and DOUBLE LAYER. SINGLE-LAYER DVDs can hold up to
4.7 GIGABYTE and DOUBLE-LAYERED DVDs CAN HOLD DOUBLE DATA. On the other hand, there are 25
GIGABYTE on SINGLE LAYER BLU-RAY DISK and about 50 GIGABYTE DATA on DOUBLE
LAYER BLU-RAY DISK.

But is there anything
special in the BLU-RAY DISK that can store so much DATA in the same size as a
CD? If we look at the CD or DVD, RED LEASER is used to WRITE the DATA. But on
BLU-RAY DISK, BLU-LEASER is used to WRITE DATA. WAVELENGTH of red LEASER
lights is higher so they cannot STORE more DATA in fewer places. But on the
other hand, the blue LEASER lights have less WAVELENGTH, so they can store
more DATA in less space.

BLU-RAY DISK was first used
during the HIGH BIT RATE movie PUBLICATION. If we want to see a 1080P UNCOMPRESSED
movie, we can get it through BLU-RAY. Even a 4K movie publication can be done on
BLU-RAY DISK. If you buy a movie BLU-RAY DISK, you get the best quality of that
movie. BLU-RAY DISK got its popularity when SONY brings SUPPORT to BLU-RAY DISK
in their PLAYSTATION-3. At that time, the Internet was not very fast like today. Therefore, the
only way to buy GAMES was BLU-RAY DISK from the market to play big games.
SUPPORT of this BLU-RAY DISK can be seen today on SONY’s PlayStation.

But now the use of BLU-RAY or
any OPTICAL DRIVE is slowing down. Because we are currently using MEMORY CARD,
PENDRIVE, FLSH STORAGE, PORTABLE SSD, and PORTABLE HDD are all of them. Because they
are much faster than OPTICAL DISK & DRIVE and are much easier to use.
Almost all of these PORTABLE DRIVES are powered via USB. Several years ago, we
even bought DVDs or CDs to watch movies. But today, no one buys a DVD or CD to
watch movies, as AMAZON PRIME and NETFLIX, the ONLINE MOVIE STREAMING SERVICES
move onto the internet. There is also PLATFORM like YOUTUBE where anyone can
watch or show videos on their own.

For this reason, an OPTICAL DRIVE
SYSTEM like BLU-RAY DISK is slowly losing.
