That is, errors (indeed frequent errors) could be made during the reading. CDs with data and CD reading mechanisms are not faultless. Each sector has 2352 bytes.ĭATA CDs occupy only 87% of all sectors (700MB of 807.5MB or 650MB of 746.9MB).
Real maximal size of 700MB CD is: 807.5 MbĬD consist of sectors. Real maximal size of 650MB CD is: 746.9 Mb click the write button and when a message comes up, say that you want to "overburn".50MB or 700MB - is a maximal size of CD intended for DATA. I wrote the above CD at 10x which is a nice speed (not too slow, but not fast enough to cause errors).Ħ. Under "source", "browse for a file", we need to load our cue file that we created above.ĥ. From the main menu in imgburn, click the 1st of 6 options, "write image file to disc"Ĥ. Now all we need to do is burn that mix, so if you make sure your blank 90 min CD-R is in the drive. The save box appears, give the "cue file" a name and save it (just remember the location where you save it).ģ. You will then receive a warning stating that your files "exceed the standard 80 mins. Drag the files you want to burn (imgburn supports the most popular audio formats including the high quality FLAC format).Ģ. Open imgburn and go to the "tools" menu, then select "create cue file". I'm assuming you are making the CD from files stored on your hard disc, since you wouldn't be using a 90 minute CD to make a backup of another CD, as there aren't any commercial CD's that exceed 80 minutes).ġ. I've done a quick guide below of how I created the above 87 min CD. The software I used for burning the CD is the latest version of imgburn (an excellent freeware program) and I just used my laptops optical drive (which is around 3 years old). I have just finished listening to my first CD from this batch, clocking in at over 87 minutes and it played perfectly.īefore buying these discs, I didn't know that my laptops optical drive supported "overburning", but I was aware that a lot of drives made in the last few years support this feature.
Like the other reviews state, 90 mins isn't standard spec therefore a lot of writing software doesn't support it. This review is from: Verbatim 43586 CD-R High Capacity 800MB 25 pack (Accessory) I have now added to my original review a very helpful method supplied kindly by D Brown which will allow you to overburn without too much effort, and i can confirm does work on all 90 min cds :. be prepared to spend time and money or just buy 80 min cds.which are much less expensive if you can be bothered to search out how to put 90 mins on one cd then buy is a lot of effort.dont think you can just buy these and put 90 mins on, you need to check out if you can overburn using the machine and software you have already. Unless you have the correct burner and software these discs will only burn 80 mins.
