A intense laser burns "micro-holes" in the film to represent the data...

A low intensity laser reads the spaces the high intensity laser left behind because the film casts back a reflection

DVD's work very similar; one low intensity layer and one high intensity layer. Furthermore, the laser makes much better use of the surface space so the DVD can hold more data

Ok i asked before if my drive will burn both dvd and cd. the answer was yes. but when i installed the drive and ran my dvd creator program. it said this drive is dvd read only.


Hi mikey7420 ,


The drive name itself is the clue to know whether it can burn dvds or not.

  • In your case it's a CD-RW (read and write or rewritable) and DVD-ROM (Read only memory and not read and write or rewritable as in the case of CD)
  • Perhaps the one who told you did not understand your question properly , and understood it , in the sense that it can read CDs as well as DVDs , as far as Dvd-ROM drives are concerned many shopkeepers who are especially new working in the shop just make a guess and answer our question which could lead to this misunderstanding or incorrect information being passed on.
  • So the next time you buy a DVD drive which should have a read and write functionality as well , then look up for a CD_RW,DVD-RW drive.
  • Also remember that DVD-RW drive can by default read and write CDs as well , but it's not true for CD drives..
  • So usually a DVD-RW drive can read and write Cds as well as DVDs but a CD-RW drive can either read or read and write a DVD depending on whether it's a DVD-ROM or DVD-RW.
Hope this helps.

I have a LG CRD-8484 B cd rom drive on an emac power pc 800 mhz, do you know if this device reads dvd or not at all?


A CD-Rom drive will not be able to read a DVD because DVD and CD drives use lasers of different wavelengths to read discs.

Hard drive not Reading CD-R Discs


First off. Your hard drive cannot read CD's. Your CD-ROM is not reading CD's. Well a few things can be wrong there. 1. The CD-ROM is dead 2. The drivers for the CD-ROM needs updating 3. The CD that you are trying to read is curropt or damaged.
Start checking to eliminate and let me know.

Dvd ,cd worn't work


the driver should allready be installed with windows

What type of problem are you having with the drive?

Does the drive read CD's but not DVD's or niether one?

Did the drive work fine and suddenly stop reading just DVD's but still reads CD's most of the time?

Or is this a new drive that hasn't worked at all yet?

for CD use the driver should allready be installed with windows and almost never needs to be installed seperately

for DVD playback in windows XP you will need to install some sort of DVD driver into the system like power dvd or windvd or you can download DVD support for windows media player here : http://www.microsoft.com/windows/windowsmedia/player/plugins.aspx#DVDDecoder

But I would need answers to some or at least one of the following questions before being able to help any further

1. What type of problem are you having with the drive?
2. Does the drive read CD's but not DVD's or niether one?
3. Did the drive work fine and suddenly stop reading just DVD's but still reads CD's most of the time?
4. Or is this a new drive that hasn't worked at all yet?
5. What operating system are you using?

I hope this info helps (please let me know if it does not)

CD/DVD DRIVE DOES NOT READ PROPERLY


Really the ONLY thing one can do.. is replace the unit with another know good working one.. IE:New. Usually a GOOD CD/DVD will instantly & always work... it will be picked up by windows and then the appropriate "Drivers" installed. As an IDE CD/DVD is "Generic" it generally doesn't require a "Special" Driver, so windows uses it's "Own" driver. Therefore generally if it's showing as OK in Windows, but is NOT going... then, usually, as I said, it is kaput.. for some reason... usually the laser Diode or Quadrant detector...
