80 Min CD's

[rhosk]

Just a quick one: Should it make a difference in playing the 80 min CD's versus the regular 74 min CD's in the players? Specifically VCD in DVD players? I'm thinking no, just wanted some opinions. I read somewhere that some players won't even play 80 min CD's. If you don't over-burn, does it make a difference?

80 minute discs and above are slightly harder for your player to follow the track because the pitch is smaller - the spiral that makes the track that the laser follows is that much narrower and CAN (but rarely) cause problems... mainly if the media is dirty or naff.

Plus, VideoCD's are written in a different mode to regular CD's and have less error correction on them, which means if there are defects on the disc there is less chance of the player being able to rectify it before the content starts becoming corrupt in the eye of the decoder.

If you can get away with 74 minute discs in preference to 80+, it won't hurt you to do so. In fact, I remember the days when 63 minute discs were the norm ! And Yamaha's Audio Master mode pulls a similar trick by making the pits and lands larger thus shortening the playing time of the disc but reducing jitter at the same time.

With modern recorders and their dampening and new players with better error correction and buffers on them, it shouldn't be an issue but yes, there is a difference with the longer length discs that can be detramental.

Very interesting..appreciate that.

Old DVD Players (1st generation) will probably not be able to play 80 min CDs. Old DVD players are very choosy in media materials as well.

Nowadays cheap DVD players such as Electrohome, Citizen, Norcent Players etc. can play 80 minute VCDs or SVCDs with 800MB movie burnt on them.

It's funny you mention some of the players as I have 2 Norcent DP300's coming. Supposedly a VERY versatile player and all I have at the moment are 80 minute CD-R's, along with DVD+R/+RW's. Thanks again for the insight.

Good point, that - my DVD player will reject the majority of CD-R's regardless of size.

It will work with all RW, however, and type 8 dyes from the likes of Princo and their OEM's to Datasafe.

Garryheather,

Your machine will not accept a VCD-SVCD burned to a CD-R, but will a CD-RW?

I'll have to try that, as a Samsung (my daughter's) will not accept any of my converts on CD-R, no matter the format.

Will have to re-encode, I think all my RWs are 70 minute, but no biggie.

Thanks.

Correct - my DVD player is a Sony, and it's very picky about media.

VideoCD's / Super VideoCD's work perfectly when put onto CD-RW's.

As I mentioned in my earlier post, Princo Type 8's work perfectly too, and they are available in 80 minutes. Most CD-RW's are indeed 74 minute, which is a pain in the butt, so maybe if you can find a supplier who stocks Datasafe media with the white tops and can let you have a sample, it might be worth you trying those if re-encoding is undesirable.
