difference between dvd media

DVD media is resistant to scratches, but is limited to a single level of error correction. DVD media is durable, and has a very long shelf life, but single disks have a limited capacity, and are not fault tolerant. If the disk fails, all the data is lost. DVD media is most sensitive to heat and most players have a great difficulty playing disc with minor scratches or dust.

DVD media is sensitive to dust and fingerprints. Carefully handle media by its edges only.

Discs that were written on set-top (that is, TV-attached, rather than computer-hosted) DVD recorders, are written in DVD-VR or DVD+VR format, which differ somewhat from DVD-Video in the way the data is recorded on the disc. DVD-Video discs written to DVD+R and DVD-R are functionally identical, and will pose no problem for duplication, regardless of which kind of source and destination media you use (i.e., you can write from DVD-R to DVD+R and vice versa, and in a multi-disc tower duplicator, you can even write to a mixed set of source discs from both camps). Discs are made to perform at an ideal rotational speed, which is where write strategy originates. The disc will perform best up to a certain speed, and the drive will not permit any faster. Disc copy will erase and burn a CD-RW. Toast crashes when trying to earse of burn a CD-RW.

Data is written to a DVD in a different manner from the way that it is written to hard disk. When your PC writes data to a hard disk, it writes data in blocks. Data reliability is very important now that blank DVD and CD media costs a lot less than it used to, but some cheaper discs are very poor in quality. Data can be sequentially recorded in each RU, in sequence. When data has been completely recorded in an RU, RU metrics can be computed.

Fake media is often bad. If you ever purchase good media like Ritek, TDK, or Maxell, and the results are bad, check to see if the media is authentic. Fake media is often bad. If you ever acquire good media like TDK, RITEK or MXL, and the results are bad, check to see if the media is legitimate.

Burning it using DVD-Video will use UDF 1.05, which is only supported by newer models. Using UDF 1.02 will ensure that your disc can be played back by just about any standalone unit because those new models that support UDF 1.05 will also play UDF 1.02 discs. BurnMaster? 16X 4.7GB DVD-R Discs are write-once recordable DVD discs that offer extremely high storage capacity. Once recorded, DVD-R discs can be played back in all DVD-ROM drives and DVD-Video players. Burn a DVD of your home videos and give it a try on your home player. If it doesn't work, bring the DVD with you to the local electronics store and test it out on the latest players.

Burn up to 4 hours of HD video on a Blu-ray disc without quality loss and then share it with your customers or send your high-quality master for replication. New Blu-ray technology allows you to archive large amounts of data, audio asset libraries, raw video shoots, image files or complete multimedia projects on long lasting BD media - at a low cost per GB.

CD-RW/DVD-RW media is designed in such a way that it can handle only limited number of writes, making discs very unreliable during intensive and/or prolonged use. CD/DVD recording is also relatively slow. CD-RX discs are fully compliant with the Orange Book standard and are readable by any standard CD/DVD reader.

DVD-RAM discs are sold with or without cartridges. Originally they were sold only in cartridges but now some RAM-compatible devices don't even support those discs anymore. DVD-RW may be recorded to up to 1,000 times . Unlike CDs, not all recordable DVDs will play in all DVD players (due to different standards over the years). DVD-R (A) is not seen much nowadays is much more expensive than DVD-R (G).

DVD-RW will be written no faster than 6x, while DVD-RAM will be recorded at 5x speed. DVD-RAM is regarded as the most reliable of the re-writeable formats due to the fact it incorporates an error checking mechanism and can randomly access in reads as well as writes, hence its name. Like DVD-/+RW the technology revolves around a phase change layer sandwiched between polycarbonate platters, however the layer in DVD-RAM uses metallic elements that the laser heats at varying intensities to magnetically polarise.

General consumer players may not like one or the other. I found the opposite with my old player, and a few friends' players. Generally, people want to buy discs that will allow the burner to write at its maximum speed, but buying media rated at 24x is pointless if the DVD player has a maximum write speed of 8x. Moreover, if the 24x media is not backwards compatible to 8x, the player won?t support the media at all.
