My CD burner doesn't burn at 52x

[lynx]

If they were reading/recording at 52x CLV you may be right, the rotational speed when recording near the centre of the disk would have to be over 3 times faster than it is at present. In other words probably in excess of 10000 rpm.

I don't know whether this would cause the disks to actually 'fly apart', but I don't think I would want to risk it.

Cd read speeds have not increased much in the past few years for this very reason, vibrations and high rotational speeds mean higher error rates, making it almost impossible to get a meaningful performance gain.

And of course errors when writing would be unacceptable.

Im not saying they will fly apart on first trying, but it makes the disc crack, and of course, if its spinning, and it cracks all the way through, what do you think will happen?

Happened to an old game disc of mine, not due to read speeds or anything, but it cracked, and umm, yeah, back goes the CD drive to the factory.... Made horrible grinding noises, and it seemed to be scratching up CD's after that, which didnt suprise me, seeing as how I only pulled like 3/4 of the cd back out......

The drives which have recently come on to the market now use CAV for recording, which allows them to record at higher rates at the outer edges compared to the centre. So whilst they are physically capable of recording at 52x speed, they only do so at the outer edges of the cd, inner areas are likely to be recorded at much lower speeds (perhaps only 16x), and the average for a full cd will be nowhere near 52x, perhaps 32x or even worse..

If you are measuring performance by the time it takes to record the disk, this may be the effect you are observing.

mine is Brand new and it says CLV...i am measuring it based on the Max. Read speed that the Prog says (in the dropdown box that you can change the speed). i don't know what is going on i didn't have this problem with my old cd burner. it burned at it's max fine...even though it was only 12x

You may got it wrong in first place... try changing it..
I had a SONY (OEM) .. and it really wasn't a sonmy.. so i got an LG, and presto!.. works just fine.

Strictly speaking, they do work at CLV, it would be virtually impossible for them to adjust the recording rate to work at true CAV. But the CLV is not constant across the full width of the disk.
It is actually what is called Zoned CLV, in other words the width of the disk is split into zones, and they work at a particular speed depending where on the disk they are recording.

What software are you using ? If it is Nero, make sure you have run Drivespeed to set the drive parameters.

Otherwise, if the drop down box says the maximum speeed is lower than you are expecting, you probably have a problem with your media, this information actually comes from the media itself.

Or of course, you may need to get a later version of the software if it doesn't recognise the possibility of high speed media.

yeh 52x is the maximum rated for ya drive and that will depend on the discs u using and the source it reading from being able to keep up ie ya cdrom drive or harddrive. it very unlikely that you will get it to burn at 52x, its a ploy by manufacturers to buy there kit. fastest ive ever burned at was 40x and that was copying data from my hard drive using nero. anyway 32x is quick enough aint it? i mean my car will do 150mph top but i never gonna see if it will!

i actually burn at 52x rather a lot

i have not had one cd which doesn't work, be it a music cd, data cd or video cd...



p.s. what kind of car you got? sounds pretty fast...

alfa romeo 156 2.5v6, had since new, 4yrs old now and its italian so its always been rattle'ee and bit temperemental, but i love the fact i can still get out of it with a smile on me face

alfa v6's are some of the best engine's in the world

the sound of them is fantastic

nice car

p.s. who cares about squeaks and rattles when the engine sounds that good, i suppose...

Not more car spam, please...

got to do with 4 different issues -

1st: the speed the cds can be burned....most right now are 48x
2nd: ur HDD rpm.... usually a 7200rpm hdd will get the job done
3rd: ur RAM....if u wanna burn FAST, u need to have at least 256ram....since the buffers are actually ram buffers
4th:the burner.... if it has buffer underrun protection its better cuz it burns fast and easy without a hassle
