How to correctly identify A-class CDs
(1) The most important thing is to look at dyes! Ask the store owner or manufacturer for details!
(2) Whether the edges of the CD are rough ~ Whether the manufacturer is vague or not!
(3) whether the CD dyes (burning surface) are uniformly printed ~ If there is any defect, do not buy it!
(4) CD surface thickness ~ We recommend that you select thick labels! But it is a load on the drive and burner!
(5) CD transmittance ~ The less light the better! In this way, the burned CDs are indeed read on the drive!
(6) Is there any ripple pattern commonly known as within 5 centimeters of the disc burning surface radius! Read load on the drive!
(7) check whether there are common Gears under the 5-cent external reflection of the disc burning surface radius! If yes, it is not true for the burner!
(8) There are more than three stars or re-prints in the cd id area ~ It is made by a rotten factory above Samsung!
(9) colors of burned and unburned sections ~ The less the color, the better the CD !!
Use of optical discs of various colors
1. Water blue)
With the latest data lost protection technology, bufferunder run is greatly reduced, so it has strong stability in one-to-one and one-to-many 1x-12x burning mode.
The best burning format is: Data)
2. Omega black (black)
Pure black material, can prevent light damage when the organic dye, greatly prolong the life of the CD-R, save longer time.
The best tutorial formats are games, Data, MP3, and PS2)
3. Purple (purple)
Can prevent the damage of light in the organic dye, greatly prolong the life of the CD-R, save for a longer time. The best recording format is: games, Data, pS2)
4. apple green)
The organic dyes are extremely sensitive to weak signals and can expose the sound domains of burned music. They can be said to be especially designed for digital music.
The best burning format is: Digital Audio, music CD, and data)
5. metalate red (metallic red)
Laser Light can completely pass through, so that the CD-R receive signal perfect.

The burning surface color is the same as that of a normal VCD. In this case, the "crosstalk frequency" is very low, which can minimize the appearance of lines or mosaics when reading files.
The best burning format is: video files (VCD, MPEG, file)
Differences between DVD-R specifications and DVD + R
DVD recorders are becoming more and more popular. when buying a piece, the boss will always ask you to + R or-R
I just saw a detailed introduction to this article and shared it with you.
In view of the DVD-RAM card design, coupled with the inconvenience of DVD-RAM, can not be widely used in DVD-related household equipment, DVD-RW is born. It is also the only standard specification recognized by the DVD forum, in addition, because the specification of the DVD-R/RW is set by the World Association of DVD makers, is also the most future expansion of interchangeable specifications.
DVD-RW full name for DVD re-recordable, thinking is override type DVD-R, as the name suggests it is like a DVD-R function, but can read and write repeatedly, a bit similar to the extension of the CD-RW, its specifications are dominated by pioneer and the capacity is 4.7 GB. nowadays, DVDs with high quality and sound quality enable a new generation of entertainment. in addition to the home-type DVD player, there is another little-known aspect of the DVD. CD audios, CD-ROM, and even CD-R/RW have been widely accepted by the public, but now we can make our own DVD! Whether it is connected with the TV video, and the PC connected to the DVD to record their own image works, etc., are no longer a dream, these are the new entertainment functions provided by DVD-RW. at the same time, because of the specifications that can be repeatedly written, the user can be used as a pre-recorded DVD film, try to put the first effect in the DVD tray, and then decide to burn into the DVD-R disc, although not as good as DVD-RAM for non-linear access, but the cost and reliable image record for its biggest advantage
Due to the increasing demand for a large amount of data, DVD forum in the Development of DVD-R specifications, take the following four points as the basis:
1. DVD-R is a new type of record system with the same CD-R.
2. After recording the DVD-R optical disc, It is interchangeable with 100% of the general DVD dial-on.
3. Supports multi session recording
4. DVD-R optical discs have extremely high cost/performance values.
DVD-R is led by pioneer company development can write a DVD specification, the earliest development of the disc capacity is 3.95 GB, and later developed a 4.7gb DVD-R disc, version 2.0. pioneer after the launch of the DVR-A03 burner, reduce the burner record head costs and disc dye costs, making DVD-R prices popular, the current application of DVD-R is mainly DVD-R for general, that is to provide general consumer use, on the market can easily buy blank DVD-R, is generally DVD-R for General disc, and for Version 2.0/4.7 GB specification.
DVD-R application?
The use of DVD-R is like CD-R, can be used to record the DVD image and data, in addition to the PC burner, Pioneer also launched a DVD-R storage media for home audio and video recorder, such as DVR-2000, DVR-7000 these household equipment, so that DVD-R/RW can completely replace the past shadow tape recorder, get high quality, search fast, easy to carry, high compatibility of the film is no longer difficult.
DVD-R Development Status:
Various manufacturers are not actively compatible with the production of DVD-R burner, video recorder and other related products, such as Japan Panasonic in its DVD-RAM burner and recording machine can be compatible with the burning of DVD-R, DVD-R has become the next generation of mainstream storage media situation clear, the current disc price is currently the lowest cost, the user acceptance of the highest storage media. all recently launched burners now support DVD-R burning specifications.
What is DVD + RW?
DVD + RW is jointly launched by Sony, Philips, richo, and HP in Japan. After evaluating the DVD-RW system led by pioneer in Japan, it decided to push another independently-owned DVD system-the DVD + RW specification. However, this specification is not officially recognized by the DVD forum, so the DVD + RW is a bit embarrassing, although it emphasizes that it is interchangeable with other DVD family members, but it was rejected by the DVD family. The original DVD Forum still does not recognize the DVD + RW system until now. Therefore, although the DVD + RW is currently designed to be compatible with other members of the DVD family, it is still not officially recognized by the DVD forum, and its Registrar only marked with RW. the latest specification is released for the DVD + RW version 2.0, with the focus on achieving a high degree of interconnectivity with the DVD player so that it can be played on the DVD dial. and has a non-linear access architecture similar to the DVD-RAM, which can provide random access to storage data. however, due to the late development period, the cost and visibility of the DVD + RW optical disc are low. as the DVD alliance has abandoned the 1.0 gb dvd + RW version specification, it is currently available in the market, it is definitely the latest architecture of DVD + RW version 2.0.
What is DVD + R?
Since the DVD alliance has developed other excellent systems independently regardless of the original DVD forum, it will be no longer so brittle. In the aspect of writing a DVD at a time, it will also adopt a path independently designed and constructed by itself, release DVD + R specifications, and DVD-R do not show signs. Because of this, DVD alliance, headed by Sony, Philips, Ricoh, Japan, and HP in the United States, also decided to give up the DVD-R architecture recognized by the original DVD Forum, another new method-DVD + R Architecture.
