History of Blu-ray
Presently, the available high definition medium is Blu-ray. Although the majority of the population is aware of this, they are not knowledgeable on the actual history.
Blu-ray was initially one of the answers to the need for HD discs. When HDTVs were introduced in the late 90s, a format was needed to go along with them.
The market did not then offer any medium that could store large amounts of data, which was necessary for HD. Thankfully, there was a relatively easy solution to solving the problem, which was utilizing a blue laser.
Shuji Nakamura is responsible for inventing the blue laser diode. This was an efficient version of the already available blue lasers. Blue laser diodes are vital components of both Blu-ray and HD DVD discs.
Two large corporations, Philips and Sony, came together to develop the Blu-ray disc. Before arriving on the name Blu-ray, they invented other predecessors known as DVR Blue and Ultra Density Optical.
The prototypes were further developed and perfected until the beginning of 2002. It was then that the Blu-ray Disc Association was launched by less than ten initial members.
The introduction of Blu-ray may have been a bit premature, as it was two years later that the format actually was finished. Even then, it took one more year for everything to be complete.
Millions of dollars were invested in the Blu-ray project, and the return was exceptional. Blu-ray is the only high definition format and is expected to hold that position.
