A trip down memory lane.

In 1979, Philips and Sony, through partnership, successfully developed the Compact Disc in 1983. A spin-off of Laserdisc technology.

While Laserdisc was too big, the Compact Disc, or CD as it is called today, was small and was a great technological marvel because at a diameter of 12cm it could hold a 74-80 minute audio capacity and a 650-700 MB data capacity.

With the advent of the CD Writer in early 2000, we have used the CD for audio materials and file backups. CDs have been widely use for almost anything; audio, videos and even greeting cards.

All of that changed when the DVD arrived. DVD, also known as Digital Video Disc or Digital Versatile Disc, is an optical disc storage media format, and was invented and developed by Philips, Sony, Toshiba, and Time Warner in 1995. Its main usage is for video and data storage.

It has the same physical size as the standard CD but packs a 4 Gigabyte storage capacity. It comes in different storage capacity sizes and is pegged at 17 Gigabyte at a maximum. The DVD has also been used to make HD Videos, Hi-Def Videos using HD DVD - a different capacity format.

The future.

Blu-ray Disc is also an optical disc storage medium designed to succeed the DVD format. The format has a 12 cm (same as DVDs and CDs) diameter, 25 GB per-layer optical disc, with dual layer discs (50 GB) the norm for feature-length video discs and additional layers possible.

The name Blu-ray Disc refers to the blue laser used to read the disc, which allows for six times more storage than on a DVD. The term Blu was used because blue is commonly used in English and therefore not registrable as a trademark.

Blu-ray Disc was developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. Every hi-definition game involves a Blu-Ray disc as its medium.

Technology is really moving forward and fast. What you thought impossible is now possible.

I can still remember when I used to play our gramaphone using a vinyl record and was fascinated on how the audio data was encoded there. Now having a CD or DVD that packs a lot of data is a common thing.

I say let's keep moving it forward with the web and digital content and delivery as the next great medium.
