Whenever I burn a CD using Nero I can skip tracks, fast-forward,
reverse, etc., in all my machines except one CD-player which is 10 years old. I would like to get round this problem because some people I share my music work with also have older CD-players. I did a bit of googling and found one piece of advice which said that for the sake of older CD-players burn as slowly as possible because that would make a deeper indentation while the laser is burning and older CD-players expect a deeper indentation. The recommendation was to burn x12. Well, I went one better and told Nero to drop from my normal x48 to x8. But it didn't make the blindest bit of difference. I can still only play CDs (which I make with Nero 6) on my older CD-player by letting them go all the way through from start of the disc to the end. Sometimes if I try to skip a track it will play the track I skip to, but usually the LCD display just blinks and nothing plays. Any ideas, please? Thanks. Ellie. |

The obvious first step is to get rid of the old CD player - they cost almost nothing these days, and there is really no reason to hang on to one that can't cope with CDRW (CDR should be very easy). And just to put you straight on a technicality. It is pressed CDs that have indentations. They are a quarter wavelength deep, and change the brightness of the returned beam through interference with the reflection off the front face. A CDR is simply a dye that has its color changed, and the beam modulation is just through albedo at the dye surface. There will be an optimum speed for these - slower is not always better. d -- Pearce Consulting http://www.pearce.uk.com |

Take care on your choice of blank disc. Many look green when blank and go blue when written - older machines don't like these. Go for a disc that is silver when blank and slightly goldy when written - DataSafe or DataWrite (from computer fairs) I find to be some of the best. Having said that some machines just will not get on with written discs - older JVC and Hitachi are notorious for it. -- Woody harrogate3 at ntlworld dot com |

The recommendation was to burn x12. Well, I went one better and told Nero to drop from my normal x48 to x8. But it didn't make the blindest bit of difference. I'd recommend that you attempt to locate CD-R blanks which are more rigorous about providing full CD-player compatibility. Modern-style blanks tend to be optimized for high capacity (720 MB / 80 minutes) and for fast burning. The former means that the pits and lands burned into the groove are relatively close together, as are the spirals in the track (right at the lower limit of the Red Book spec). The latter means that the dye layer is relatively thin, requiring only a short exposure to the laser. Older CD players often have difficulty with such blanks, once burned. The close track and pit/land spacing can (I believe) present difficulties for the tracking servos, and the thin dye layer has a lower reflectivity at the read-laser frequency and results in a weaker RF signal being detected by the photodiode. Older CD players may lack an automatic gain control in the RF-read circuit, and as a result they don't get a strong enough signal for their servos and data-recovery circuits to process reliably. If you hunt around, it's still possible to locate a few brands/types of CD-R blank which are specifically optimized for low-speed burning of audio material and for CD-audio playback compatibility. These blanks will be of the "650 MB" type (good for up to around 70 minutes of audio) and will specify a relatively low maximum-burning speed. They'll also be more expensive than the mass-market stuff, since they're being made for a niche market by a relatively small number of companies who are more concerned about product quality. Another thing you can do, is to try a batch of standard (higher-speed, data-grade) blanks made by some of the first-tier companies. Mitsui, and Taiyo Yuden have very good reputations for disc quality, and I'd trust their products (if genuine - there seem to be some counterfeits around) over blanks made by the second- and third-tier companies (CMC, Ritek, and so forth). Try getting yourself a few Mitsui or TY discs from a reputable on-line supplier, burn them at a relatively low speed, and see if they work any better than the ones you have been using. Be aware that a lot of the consumer-brand-name discs sold in the US are simply OEM'ed from other companies. A well-known brand name is not a guarantee of quality, alas. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

Question of the day here, Don. Is there any way of determining which speed results in the best burn for a given CDR (other than finding a borderline CD player)? I understand that there are some CD-R burners (e.g. some Plextor models) which have the ability to read back a burned disk, and present a summary of the amount of low-level error correction required to recover the data. The higher the number of C1 errors, the poorer (in general) the quality of the burn. Another approach is to use an oscilloscope or spectrum analyzer to monitor the strength of the RF signal being detected by the laser-read mechanism (or, equivalently, monitor the behavior of the playback unit's RF automatic gain control). The stronger the RF signal, and the cleaner the "eye" pattern, the better the burn is. You'd need to run this experiment at various burning speeds, on a given CD-R burner, to figure out which speed produces the highest-quality burn with that batch of blanks on that particular burner. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

I would like to get round this problem because some people I share my music work with also have older CD-players. Burn as slow as your burner will let you. The best burner I have will burn Audio CD's at 4x. The next best I have only goes down to 8x. I did a bit of googling and found one piece of advice which said that for the sake of older CD-players burn as slowly as possible because that would make a deeper indentation while the laser is burning and older CD-players expect a deeper indentation. The recommendation was to burn x12. Well, I went one better and told Nero to drop from my normal x48 to x8. But it didn't make the blindest bit of difference. Can you go slower than 8x? If not, then your CD player is likely so old that it simply can't read today's silver, high speed, CD-R's. For that old of a player, you might be able to use older blue CD-R's and get it to work, but those would also need an older burner (I used to use a 2x burner with blue CD-R's). I can still only play CDs (which I make with Nero 6) on my older CD-player by letting them go all the way through from start of the disc to the end. Sometimes if I try to skip a track it will play the track I skip to, but usually the LCD display just blinks and nothing plays. You're burning "Disc at once", right? If you're burning "Track at once", I'd change that setting. Also, make sure you finalize or close the CD. Don't leave it "open", which would let you write more data to it later. If none of that works, replace that ancient CD player! You can buy a home DVD/CD player these days for $30. Portable, walkman style, CD players can be had for $10.

I usually burn Audio CD's at 4x or 8x. I've found that slower seems to be better for my older CD players. These are all "silver" CD's. I gave up on trying to burn for very old equipment (machines that won't take silver CD-R's). To me, it wasn't worth the hassle trying to buy the old style blue CD-R's and burning them at 2x.

Thank you very much everyone for so much helpful advice!
Well, two months ago I bought 400 discs which are all of the type which you advise are of the 80-minute variety and unresponsive to a slow burn and I am sure as hell not going to dump them and fork out for the better ones, so, as you all suggest, anyone with old CD-players who gets hold of my discs will just have to move up to a more modern player! And I'll keep my fingers crossed for no complaints from them! Thanks, Ellie. |
