Backed up music CD's will not play on older Hi Fi

I have tried to back up some of my music CD's using Nero 5.5
No problem copying or playing back on my computer, car stereo or Sony surround sound system.

They will not play, however, on an older (about 10 years old) Technics Hi Fi system that I sometimes use.
Is there something I can do or is this Technics system just too old to read these formats?

Thanks for your help.

You gureesed correctly - some older Hi Fis will not read CD-Rs. I don't know of a way around it...

It is quite common for older CD players not to be able to "see" home burned CDs because of the method of production. Commercial pressed disks have a very highly reflective surface so only a relatively low power laser is needed to read them. Burned disks have a much less reflective reading layer and the lower power of old lasers cannot cope with or "see" the low reflected light level.

The newer the CD drive, whether audio or ROM, the more likely that the manufacturer has enabled it to read modern media.

The specifications normally detail in full the type of disks the drive is able to read.

As -pops- says, it boils down to the power of the diode laser and the optical device reader. Maybe a hi-fi forum could point towards upgading these items - a specialist job certainly.

For information, I have an old Technics Hi Fi system in which the CD player has died. I bought a cheapo Philips Expanium MP3 player (pocket sized) and plugged that in place of the 19" rack mounted CD player. On a purely subjective basis, the new player sounds infinitely better than the old system and is more versatile as well.

Machins,
You didn't say if you are using cd-r or cd-rw disks.

You didn't say waht speed you burned your cd's at. Try buring at the slowest possible speed - sometimes but not always this solves the problem.

As far as I'm aware the track info for a CD is burned in the centre of a disk, and the info for a CD-r disk is burned on the outer edge. So older players look to the centre of the disk for the CD info and if it is not there then the disk cannot be read by systems that were made before CD-r's were common.

Not heard of that one before Kryten but I'll bow to your knowledge if its true (-:

Kryten's information won't make it play though<;-))
