i know this is a silly question, but since you brought it up... if i have 74 min cdr's.. how do i overburn 80 minutes? how can i tell if the cdr will have 80 minutes? when i get "info" on my cdr's they only "say" they have like 74:24.18 etc.. but not 80 minutes.
thanks in advance for any help.
i found some info.
BUT... does this mean you burn coasters if it just doesnt fit? i mean the only way to find out how much space you got on a 74 or 80 min cdr is dependent on what you try and burn on it right? and if you try to burn 78 minutes when the cdr turns out to have 77 (after overburn) does that mean you get a coaster?
OVERBURNING & 80 MINUTES MEDIA
Overburning
Overburning is the possibility to burn more than 74 minutes on a regular 74 minutes disc. How is that possible? A blank CD-R contains a pre-groove, which is used for calibration and tracking by the writer. On this groove the data will be burned. The length of the pre-groove determines the length of the CD. Normally a CD-R is 74 minutes, but the groove is always a little longer. This allows you to burn more than 74 minutes on a 74 minutes disc. Most discs are capable of holding about 77 minutes. Thus if your burner supports (Plextor, Yamaha, Teac,...) overburning, you can write 77 minutes (sometimes even more) on a regular disc. Overburning may seem a little bit overkill, but if you are planning on copying (backup for own purpose
) recent PC or PSX games you might need overburning because some games are made larger than 74 minutes as a kind of copy protection. Note that some CD readers have problems reading overburned discs (but I never had any problem with it). Anyway with the low prices of 80 minutes media overburning isn't really very important anymore.
80 minutes CDs support
Since many (prerecorded) CDs are larger than 74 minutes there are also 80 minutes CDs available. Are this certified overburnable discs? No, a 80 minutes disc is not overburned (but can also be overburned up to 83 minutes!). The pre-groove is simply wound tighter (thus it's longer). An often made mistake is thinking that a burner capable of writing 80 minutes discs can also overburn or vice versa. Both are not related to each other.
