overburning

[murphy1]

Hello, don't know if this is the right area to post, but.....

I have a client with a mitsumi cw-7582 burner,
and uses adaptec cd creator 3.5. he is trying to create a video disk, using a .dat file (mpeg) It is telling him that he is 9 mb to large. does anyone know if this drive can overburn, and if so, how would he do it?

It came off of a cd-so it should fit??? anyone know??
thanks in advance...

I use a Mitsumii writer myself, and from what I can gather, no Mitsumi drives support overburning.

Easier way is to update the firmware to the latest revision , then go out & by some 80 minute discs.

I have a Kodak CDR 4801 (Ide 8 read x 4 write) and I am also interested in overburning as I have an Mpeg Dat file that is larger than the 650 MB of a CD. The problem is that although it is a Kodak CDR it is essentially a Mitsumi (Kodak re-directs its users to the mitsumi site for drivers etc) and the mitsumi drive has the same name as the Kodak one. Anyway I will attempt to overburn a CD tonight for interest sakes using Adaptec VCD creator (Included with Easy CD Creator) and see what happens. Also I have heard that cdrwin is popular for burning/overburning so I might experiment with that too. I just hope you are wrong about these mitsumi drives Darren (But your rarely wrong so I dont like my chances) Ill keep you informed

If the video file came off a CD, you should try doing an exact copy of the CD (provided you still have it). Also, you can set your burner for video cd mode, in which a 650 meg disk can hold about 675 megs worth of video.

I use the 4801TE myself ( with the latest Firmware ) and both CDRWIN 3.7c & Nero v4.6 state that the writer does not support overburning. Most IDE writers don't ( for some reason that I am not really interested in as overburning can damage the burning laser ), but if you want to overburn the Plextor PlexWriter 4x12 or the PlexWriter 8x20 do the job superbly. Trouble is the expense in having to buy a good SCSi setup to accompany them if you want good results.

Ok after experimenting with CDR software and doing a bit of research in the process I have learned quite a bit about overburning. Am I correct in saying that overburning uses mode 2 or CDROM-XA mode, or am I completely off the mark? I have been reading up on the capabilities of the Mitsumi drive and according to the manual the supported disc formats include CDROM Mode 1, CD-DA, Video CD, CD-i, Cd Extra, CDROM-XA Mode 2 form 1 and form 2 and Photo CD's. It sounds like it should go, I think I just have to play around with setting etc a little more. Then again more than likely I am way off the mark and completely wrong, in which case just ignore my previous comment/s

I got the latest update for Easy CD Creator but it isnt even successfully creating an image of the mpeg file to burn. The file is about 670MB or so and the image created is only 350 MB. I am getting out of space errors on drive C (There is only about 350 MB free on it) But I dont know where to set the temp directory. I set what I thought to be the temp directory to a partition with 1 GB free, So I dont know why it reffering to C Drive. Any ideas about that one?

You mentioned that most IDE CDR's dont support this feature. I was under the impression that very few CDR drives now didnt have support for it. I know a couple of people with IDE drives who have successfully overburned , The drive we have here at work (Yamaha 6 read 4 write IDE manufactured in October 1997) has support for overburning. I must admit however, I wasnt aware that overburning had any negative effects on the burning laser. What sort of damage can be done, and under what circumstances do problems occur? If the risks are too high Ill probably give the whole idea a miss and use your first suggestion (invest in 80 min media) but for interest sake I would still like to know, plus Im learning new stuff in the process so it isnt going to do any harm.

Ok, I have conducted a few tests and after creating 2 screwed CD's, I was able to successfully overburn a CD on my mitsumi drive 4801TE. I needed to get the latest update for Easy CD Creator version 3.5c and used VCD Creator. So in reply to your original post Murphy1, I would suggest your customer download the latest update for Easy CD Creator from adaptec, and try using the VCD Creator that comes with it. overburning a CD should allow you access to about another 80MB ie: 730MB Total. Hope this post clears up this overburning question.

Darren: I would still like to know more about the damage you say overburning can cause to the burning laser? I assumed that it would not have any negative effects on the burning laser as it is still a supported mode of burning by the CDR and if damage could result, mitsumi (or any other CDR manufacturer) would not support it. If you could get back to me with this one I would appreciate it Darren, because I dont particulalry want to overburn if it is causing damage, thanks.

Let me get this right, if I am wrong please correct me ( I don't mind ).

Overburning involves the burning laser of the writer writing the outer edges of the cd by angling out slightly. This is not how the manufacturers designed the writers to be used. It seems to be ok if done in small quantities, but if the writer ( & this has actually happened to one of my customers )fails and needs to be RMA'd then the manufacturer can actually refuse to warranty the unit through misuse.

I don't knw much about overburning as it actuallty doesn't interest me ( sorry to be vague H-Bomber ), if I can't fit it on a standard 74min disc I use an 80min disc instead.

I will get the update to EZ-CD Creator and give it a go with the 4801TE, but why does this allow you to overburn with the 4801TE and other ' better ' burning software will not allow it to ???????

Sounds dodgy to me, but I will try none the less.

UPDATE!!!!!!

Check out this page for a list of Writers that Support OVERBURNING. Looks like the Mitsumi doesn't, but if H-Bomber would be kind enough to let us know what settings he used it would be grateful.

From the information you have supplied Darren it is definately a strange topic with varying thoughts and ideas, and yes, my CDR is not compatable with overburning according to the Nero site, but neither is the Yamaha CDR I use at work here either (CDR401) which was also successful at an overburn. (Anyone else who has had success or failure when overburning, please give us some input so we can develop a better understanding of this subject). Ok I think I have figured it out. Although I am using a 650 MB CD, I am not actually overburning the CD. Using the VCD Creator with EZ CD Creator i am able to achieve the extra storage capacity because the Cd eliminates all its error correction information. A CD copied using mode 1 or CDROM mode is standard and data tracks only contains mode 1 data sectors. A Cd Created using Mode 2, or CDROM-XA mode the data track contains only mode 2 data sectors. A mode 2 data sector can be one of two formats, form 1 or form 2. A form 1 sector contains contain 2048 bytes of user data together with EDC and ECC bytes. A From 2 sector contains 2324 bytes of RAW data (eg: ADPCM audio or video data). Ok I think that makes sense, if not check out: http://www.isomedia.com/homes/isomedia/CD/cd_rom_faq/faq_27.html
So basically only audio a video can be copied using this format and not general data. CDROM-XA is supported by most new CDR's so I dont think It would do any damage to the CDR since it it is all software based. Im not sure if this is what is reffered to as overburning or if overburning is in fact the process you described (Which isnt supported by my CDR) according to that Nero site my idea of overburning and your idea of overburning are different. Never the less I hope this clears up a few problems. I know it is also possible to create a Multisession CD which comprises of a session with an mpeg file in RAW format using CDROM-XA (Mode 2) and form 2 and also some data such as autorun information and a VCD player using CDROM-XA (mode 2) and form 1. I think I had better stop now before I start confusing myself

When you burn a VCD you don't burn it in size you burn it by length, so it your .dat file is 800megs and the mpeg inside is actually 30 minutes it will fit on a standard 74min/650meg cd
you need to get a vcd burning program I think one comes with adaptec's ez cd creator not sure though.

[Darren Wilson]

if you do straight disc-2-disc copy from vcd to 74min blank EZCD Creator will copy it perfectly using th eCD Copier part of the package, unless the person has protected it with illegal TOC's , etc
