DVD-Plz tell me what the following terms mean:?

Question

DVD+RW
DVD-RW
DVD+R
DVD-R
DVD-ROM

Answer 1

DVD+RW-able to be re-written, meaning you can move files onto and off of it.

DVD-RW is the same thing except, it only plays in about 75% off DVD players.

DVD+R- means it can be recorded onto the disc only once. Plays in probably all DVD players, computer and standard.

DVD-R is also a once recordable disc, but isn't as playable in DVD players as the DVD+R

DVD-ROM means that the files can be read only. -R- ead -O- nly -M-emory.

Answer 2

DVD+RW - Digital Vegetable **** Re Writable
DVD-RW - Digital Versatile Disc Non Re Writable that is Once Writable

DVD+R Digital Versatile Disc Writable
DVD=R Digital Versatile Disk non writable (Only Read)
DVD ROM Digital Versatile Disc Read Only Memory

Answer 3

hi, CDs (compact disks) and DVDs (digital versatile disks) save innovations which would be study via dissimilar diverse gadgets from desktops, to CD gamers to DVD gamers. yet first of all records (despite if that's track, textual content fabric or audio) must be written onto the CD/DVD. in case you think of the CD/DVD as a writing pad on which words can in trouble-free terms be written as quickly as, you are able to't re-use the comparable piece of paper quite a few cases. This correlates to a CD-R or DVD-ROM /DVD-R the place records would be written on as quickly as and then won't be in a position to be bumped off or replaced. in assessment CD-RW and DVD-RW are rather like a chalk board the place you are able to write something down and then rub it out and alter it in a while. desire it incredibly is powerful

Answer 4

DVD+RW (Means you can reuse the DVD. The did is a rewritable)
DVD-RW (Same thing as above, but a different 'format')
DVD+R (Writable DVD, can only be used one time)
DVD-R (Same thing as above, only a different 'format')
DVD-ROM (Rom = Read Only Memory, meaning you can not write to it at all, only read the information off of it)

Answer 5

DVD+RW / DVD-RW : Same thing. A digital versatile (or video) disk re-writable. You can erase the stuff you burn, and write new stuff into the DVD-RW.
DVD+R / DVD-R: A digital versatile (or video) disk writable. You can't erase the previously burnt stuff, but u can add more, if theres space.

DVD-ROM: The device which reads the DVDs.

Btw, if you where wondering wat a DVD-RAM is... its a device which WRITES onto the black DVD-R or DVD-RWs.

Answer 6

is this like some 6th grade homework assignment?

1st two are dvd rewritable
next two are dvd write once
last is dvd read only

Answer 7

DVD+RW and DVD-RW are rewritable optical disc.
DVD+R and DVD-R are writeable optical disc.
DVD-ROM is a optical disc that can be read only.

Answer 8

dvd+r / dvd-r : dvd recordable ( can be written once)
dvd+rw / dvd-rw : dvd rewritable (can be erased and recorded over numerous times)

Answer 9

REMEMBER THE early 1980s — and the battle between the two video recording formats, VHS and Betamax? For something like four years, both formats slugged it out in the market place. Customers who bought one type of player, discovered they couldn't play the other.

Sixteen years later


The wise ones waited — till 1988 — when VHS won out on sheer numbers, and Sony conceded that its Betamax format was a flop. But before that slug fest ended, millions of consumers had wasted their money backing the wrong horse.

Sixteen years later, it is sadly a replay of that sorry episode. The battle lines were drawn last week in what could well be a new edition of the `DVD Wars', as the optical recording industry seems poised to launch into another needless `winner takes all' contest between two different standards for the next generation of high density-high resolution DVDs.

Currently available recordable and rewriteable (that means multiple write/erase operations) Digital Video (or Versatile) Disks have already witnessed a small conflict that has ended in uneasy stalemate. This has seen the presence in the market, of two types of read-write DVDs, which come from the `plus' camp and the `dash' camp. The plus camp makes recordable DVDs which are called `DVD+R' and re-recordable disks called `DVD+RW'... The `dash' camp calls its offerings DVD-R and DVD-RW.

Incompatibility


`Plus' recorders will not work with `dash' media and vice versa. Fortunately the customer was not overly hassled by this lack of standardisation because makers of player and recorders quickly adjusted their technology to accept both types of recording and playing media. Last week LG advertised its `super multi DVD Re-writer' in India, claiming that it was the `world's only all-format DVD re-writer', which can read and write all six prevalent formats.

When it comes to tomorrow's DVDs the conflict has become sharper. While all current optical disk technologies (CDs as well as DVDs) use a red laser (of wavelength, 650 nanometres) to read and write data, the new format uses a blue laser (with a shorter wavelength: 405 nm).

The shorter wavelength makes it possible to focus the laser on a smaller spot, and hence pack in the data much tighter.

While today's DVDs can hold about 4.7 gigabytes of data, the next generation of DVDs based on the blue laser can be expected to hold at least five times as much: 20 GB-25 GB.

One group of manufacturers, already gearing to offer these higher density DVDs starting in 2005, has jointly evolved a joint standard for what will be known as the Blu-Ray disk and has formed the Blu-Ray Disk Association. Even while using an identical Blue laser at 405 nm, to achieve its higher densities, and the same size of disk, 120 mm — as the current CDs and DVDs as well as the Blu-Ray DVD — another group of companies is offering a rival standard called HD-DVD.

The main promoters of this specification are all Japanese companies. The body supporting the HD-DVD format is known as the DVD Forum. The single layer HD-DVD can hold 15 GB of data, while the single layer Blu-Ray DVD is promised with 27 GB.

The only important difference between the competing standards is in the coating. Blu-Ray disks have a recording layer that is 1.1 mm thick with a coating of 0.1 mm thickness.

Coating thickness


Thus they are just as thick as today's 4.7 GB DVDs where a 0.6 mm data layer has another 0.6 mm thick coating on top of it.

The HD-DVD has used the same data and coating thickness as the present generation DVD — that means 0.6 mm plus 0.6 mm. The Blu-Ray disk's data layers are closer to the surface because of the thin coating; so the laser can read smaller etchings enabling it toaccommodate slightly more data.

However the point the HD-DVD camp is touting, is that precisely because their product is identical in thickness of data layer and coating, to today's DVDs, it will be cheaper to manufacture: Existing plants will not need much re-tooling. The message to consumers was clear: "We're ready with a drive that will work with the high density DVDs that you'll be using tomorrow to store and view all your movies — but it can still work with your old CDs and DVDs".

The unsaid logic


Indeed, the unsaid logic behind going for high density DVDs is the expected boom in film-based mass consumer applications.

HD-DVD and Blu-Ray DVD disks will in all probability, require different types of players and recorders — at least to start with. Optical media manufacturers are hedging their bets and gearing to deliver either or both of these next-gen DVDs. I asked Ratul Puri, the Executive Director of Moser Baer India Ltd, India's only optical media maker for his take on the current standards `war' and this is his reaction: "As the third-largest manufacturer of optical storage media in the world, we are actively involved in R&D work on both formats and standards and are coordinating with most of the leading companies and associations in the world on the same.

"Unfortunately, from the consumers' perspective, there is going to be a bit of confusion over the two formats and the lack of clarity on any one.

"That's because larger companies and production houses are divided in their backing for any one standard. Also, unlike the case of DVD+R and DVD-R, where the same drive can read both formats, it is not yet clear whether HD and Blu-Ray will be able to be read on the same drive. Therefore, it does appear likely that we are headed for another format war."
