Does the Dvd Write Speed Affect the Speed It Can Be Read

Does the speed at which you burn DVDs take an issue on the quality?

Does the speed at which you burn down a DVD or a CD have an event on the quality, longevity of the recording. Is there whatever proof or experience that slower burn down speeds produce ameliorate results?

I never paid a lot of attending to burn down speeds. I burn at the max speed available. However recently someone told me that DVDs burned at boring speed last longer(the data stays useable for longer amount of time)

I'm curious to hear your opinions on this.

That is true to a certain extent. Faster writing speed equals less fourth dimension for the laser to affect the die layer. What'south more than of import is what recording strategy is used. Ordinarily high-speed writing uses CAV (constant angular velocity). What this ways is that the drive is spinning the disc at a fixed RPM. This tin issue in the terminate of the disc getting less exposure and so the starting time. In theory making it more susceptible to read errors. Z-CAV and Z-CLV are also very dubious, here the writer changes write speed at various intervals, which can result in desperately recorded spots.

For archival purposes, I recommend CLV (abiding linear velocity), equally it has equal exposure over the entire disc. Theoretically resulting in better recording quality. Also don't skimp on what discs you utilize for burning, use either verbatim (the "skilful" kind) or taiyo-yuden media.

You tin oft download specifications from the drive manufacturer to tell you at what speed the drive uses various writing strategies.

A very long time ago I saw a review that looked at the number of ECC correctable errors across a range of DVD burners correct later the DVDR had been written. The decision they came to was that there is a big departure between makes and models and that the speed at which you wrote the disks had a substantial effect on the number of errors introduced during the burn process. Thus their advice at the time I think was a Sony DVD author and depression speeds. I haven't seen whatever of the large review sites look into this in nearly a decade, it could be fixed, it could be worse or exactly as it was 10 odd years agone.

That is true to a certain extent. Faster writing speed equals less time for the laser to touch the die layer. What's more than important is what recording strategy is used. Normally high-speed writing uses CAV (constant angular velocity). What this ways is that the drive is spinning the disc at a stock-still RPM. This can result in the finish of the disc getting less exposure then the first. In theory making it more than susceptible to read errors. Z-CAV and Z-CLV are besides very dubious, hither the writer changes write speed at diverse intervals, which tin issue in badly recorded spots.

For archival purposes, I recommend CLV (constant linear velocity), every bit it has equal exposure over the unabridged disc. Theoretically resulting in better recording quality. Likewise don't skimp on what discs you employ for burning, apply either verbatim (the "proficient" kind) or taiyo-yuden media.

You can oft download specifications from the drive manufacturer to tell y'all at what speed the drive uses various writing strategies.

I've never seen options for these things in any software. How do you set up your DVD burner to practice CLV?

That is true to a sure extent. Faster writing speed equals less time for the laser to affect the die layer. What's more important is what recording strategy is used. Commonly loftier-speed writing uses CAV (constant angular velocity). What this ways is that the drive is spinning the disc at a fixed RPM. This can result in the end of the disc getting less exposure then the get-go. In theory making it more susceptible to read errors. Z-CAV and Z-CLV are also very dubious, here the writer changes write speed at various intervals, which can result in badly recorded spots.

For archival purposes, I recommend CLV (constant linear velocity), every bit information technology has equal exposure over the unabridged disc. Theoretically resulting in better recording quality. Also don't skimp on what discs you use for burning, use either verbatim (the "skilful" kind) or taiyo-yuden media.

You can often download specifications from the drive manufacturer to tell you at what speed the drive uses various writing strategies.

Is it possible to set your writer to use a certain fashion, CAV/CLV?

Is it possible to set your writer to use a certain way, CAV/CLV?

Unfortunately no. You have to select a speed where the author uses information technology. Usually ii(.4)x or 4x for DVD's, I have seen a few newer writers that can do 6x CLV (they practice a very good turbine impersonation... ). Annihilation over that is likely to exist either Z-CLV, Z-CAV or CAV.

If you apply Nero for burning, there is an choice to show the "real" write speed. Its buried under avant-garde settings. This allows you to apace figure out what is beingness used at a given speed. If its steady throughout the disc, its CLV. If it starts slow, and ends fast its CAV. If at that place are sudden jumps in recording speed, its either Z-CLV or Z-CAV.

i take ten yr old CDs that notwithstanding work and DVDs that are at least 6 or so years old (dont remember when i got offset DVD burner) they even so piece of work fine

how long is "long time"

ive ever burnt at max unless burning a blu ray, merely because BR costs to much to brand a coaster

I have CDs that are 20 years old and yet skillful, I take disc that were burned ii weeks agone that accept faded out to non usable.

Does fire speed affect quality, YES, The quality of device and material make a big deviation but theres is no getting around fade or failure even with the best.
I have noticed this since I got my 4x (circ 98) burner to replace my 1x (circ 96).
Noticable sound problems to this day I have come across using high speeds over lower speeds, Disc wont piece of work in some other drive, Audio quality is horrid to the signal of being flat, Bias to ane extreme treble or bass, Skip or scratching (squeels and pops) and just wont work days afterward.
Even with the introduction and video disc (DVD and BR) the same quality problem has carried over from CD with the inclusion of visual artifacts.

Fifty-fifty burn software are unlike at the same speeds.

with the introduction and video disc (DVD and BR) the aforementioned quality problem has carried over from CD with the inclusion of visual artifacts.

But at to the lowest degree DVD's and blurays have pretty robust error correction. CD'due south have about zippo. If you're really paranoid (similar me) y'all rar the files with recovery records before you lot burn them. This won't piece of work for audio CD's of form.

If you're getting visual artefacts with either DVD or bluray, I remember there is some other problem somewhere in your setup. It could likewise exist because you're using a stand-alone DVD/bluray thespian, they usually just keep reading if in that location is a disc mistake. Computer drives don't...

I can't find a source for it now but IIRC a CD contains about 2GB in total (a normal 650MB i that is). About of that is apparently data correction for the well-nigh function. They have an atrocious lot of correction on them, merely they are also exposed to the air and easily and spinning in a drive then they go pretty beat up.

I can't find a source for it at present simply IIRC a CD contains most 2GB in total (a normal 650MB ane that is). Most of that is apparently information correction for the virtually role. They have an awful lot of correction on them, but they are also exposed to the air and easily and spinning in a drive so they get pretty beat up.

A standard 650MB CD-ROM actually just contains ~784MB data with mistake correction. A CD sector is 2.532 bytes, 2048 bytes of which are actually bachelor for user data. 288 bytes are used for ECC, and the concluding xvi bytes are header information. Now, if yous're using Style ii, all 2.336 bytes are available for user data, only you completely sacrifice ECC. This might exist acceptable for audio/video, but certainly non for data.

A DVD has two layers of ECC, at the sector and at the cake level. This makes DVD a lot more than resilient, but by no means foolproof...

I'one thousand curious to hear your opinions on this.

I think that was the case a long fourth dimension ago. Maybe it still holds with bd roms.
But I've afterward comparing 8/16x writes on a few DVD rom spindles, I've come to the conclusion that 16x is slightly improve on decent quality media (Mitsubishi) and the divergence was marginal on TDK branded CMC media.
