Title: world's first DVD-R DL disc created (Feb 2005)
Post by: chrisNova777 on October 27, 2020, 09:28:18 PM

Dual layer 8.5GB DVD-R DL Disk Launched

Mitsubishi Kagaku Media Co., Ltd.

(TOKYO, JAPAN) Mitsubishi Kagaku Media Co., Ltd. (MKM) today announced the world's first dual layer DVD-R disc made to DL standards to be launched this spring.

"Sales of DVD recording drives show tremendous increases worldwide," says Shigeru Tamura, MKM Chief Information Officer. "And industry estimates*2 put demand for DVD discs in 2005 at some 2.5 billion units, which is a year-on-year increase of 79%." As users record more images and movies, data density increases and people ask for greater capacity DVD recording discs. To meet this demand, MKM launched the world's first double layer DVD+R DL discs in May 2004, which were well received in the market. Now, MKM will be the first one to launch a single sided dual layer media in the DVD-R format, which is the most popular format.

With development of this new disc, capacity of DVD-R discs is now double*3 that of conventional discs of this type. When using these new discs in compatible DVD drives, not only large amounts of data can be recorded continuously on the discs, but also the discs can be used in conventional DVD players of PC DVD-ROM drives to playback the recordings.

*1 As of February 16, 2005
*2 Japan Recording-Media Industries Association
*3 Compared to conventional DVD-R capacities of 4.7 GB, MKM's new disc offers 8.5 GB capacity.

* Data must be recorded on this product with a single-sided dual-layer DVD-R compatible drive. Other drives cannot be used.

Manufacturing of single-sided double-layer discs requires a high level of production technology to lay down the L0 and L1 layers, coat them with recording material, and place spacers between them. MKM uses proprietary DYN-AZO recording material for recording DVD discs, and application of the technology we developed for this organic recording material enabled MKM to develop single-sided double-layer recording media. In addition, as our advanced stamper technology, combined with ultra-precise substrate molding technology, achieves high writing speed and low error recording for superior recording and playback compatibility.

What is the difference between the DVD-R and DVD+R formats?
Answer: DVD-R (pronounced "DVD dash R") and DVD+R (pronounced "DVD plus R") are nearly identical formats.
The discs look the same and are both supported by most DVD-ROM drives and DVD burners.

The only difference between the formats is the way they determine the location of the laser beam on the disc.
DVD-R discs use tiny marks along the grooves in the discs, called land prepits, to determine the laser position.

DVD+R discs do not have land prepits, but instead measure the "wobble frequency" as the laser moves toward the outside of the disc.

The DVD-R format was developed by Pioneer and was released in the second half of 1997.
Companies that originally supported DVD-R include Pioneer, Toshiba, Hitachi, and Panasonic

DVD+R was developed by Sony and Philips and was introduced in 2002.
Companies that originally supported DVD+R include Sony, Philips, Hewlett-Packard, Ricoh, and Yamaha.

However, most of these companies now develop hybrid DVD drives that support both DVD-R and DVD+R formats.
They are known as DVD±R or DVD±RW drives.

When looking for media for your DVD drive, make sure it ends in "-R" if you have a DVD-R drive
or "+R" if you have a DVD+R drive.

If you have a DVD?R drive, you can use either format.
DVD-R is still more popular than DVD+R, but since they are both widely supported, it should not matter which format you choose.

DVD+R Double Layer Breaks the Next Record, 8X Recording in Less Than 16 Minutes
October 21, 2004


Technical Feasibility of 8X Writing on Double Layer DVD+R DL Proven by Philips, MKM and Ricoh   
“When it comes to DVD recording, faster is better”

The DVD+RW Alliance, a voluntary association of industry-leading personal computer, optical storage and consumer electronics manufacturers that support the Plus format for DVD recording, will present the world's first recording of 8X speed on 8.5 GB double layer DVD+R DLmedia at the World PC EXPO in Japan. The technical presentation will be based on the laboratory results of Philips, MKM and Ricoh.

At 8X recording speed, consumers will be able to create a full 8.5 GB DVD disc in less than 16 minutes, compared to the 47 minutes (at 2.4X recording speeds) using current DVD writers. 8X DVD+R DL media and drives are expected to come to market in the first quarter of next year. (early 2005)

"When it comes to DVD recording, faster is better," said Frank Simonis, Chair of the DVD+RW Alliance Product Promotions Group and Strategic Marketing Director for Philips Optical Storage. "8X DVD+R DL recording will cut the time it takes to burn a DVD+R DL disc to about one-third of what it is now. That's something consumers will like. And it's just one more example of how the DVD+R/+RW format is leading the way to the future with our ability to provide the functionality and performance consumers want."

About DVD+R/+RW

The DVD+R/+RW format is capable of recording up to 8.5 gigabytes of digital video, images or data. This equates to the storage capacity of up to eleven CD discs and the potential to store thousands of digital photographs or approximately four hours of digital video. The primary benefit of DVD+R/+RW is its two-way compatibility, meaning that DVD+R, DVD+R DL and DVD+RW media can be played in most DVD video players and DVD-ROM drives.

About The DVD+RW Alliance

The DVD+RW Alliance is a voluntary group of industry-leading personal computer, optical storage and consumer electronics manufacturers. The companies promote the universally compatible, rewritable DVD+R/+RW format that enables true convergence between personal computing and consumer electronics products.

Title: First LightScribe-Certified 8x DVD+R DL (Oct 2008)
Post by: chrisNova777 on October 27, 2020, 10:50:33 PM
LightScribe is an optical disc recording technology that was created by the Hewlett-Packard Company. It uses specially coated recordable CD and DVD media to produce laser-etched labels with text or graphics, as opposed to stick-on labels and printable discs. Although HP is no longer developing the technology, it is still maintained and supported by a number of independent enthusiasts.
