Old made in Japan 4x CD-Rs OK at 24x ?

[larry moe 'n curly]

Is it normal for 5-year-old Taiyo Yuden and Ricoh CD-R disk rated for
4x to burn reliabily at 24x ?

Nero must have misread or ignored their maximum speed ratings and
burned them at 24x (drive is Acer/BenQ 48x16x48), but they verify fine
and are readable even in an ancient CD-ROM drive that has trouble with
some CD-Rs and all CD-RWs. This was even after I left them in a hot
car one day (170F). I don't think that Nero simply misreported the
speed because each disk took only about 3 mins. to burn.

Actually there is no speed rating for CD-R on the disk itself.
It is up to the user to tell the software to go slower. If the
drive knows the disk ist may also decide to go slower.
Entierly different story for CD-RW.

This was even after I left them in a hot
car one day (170F). I don't think that Nero simply misreported the

Give them a month or two, then try again. Still, this may
be a lucky match between burner, burner firmware and medium.

It could be at the time the disks were made they were reliable at 24X.
But were marked and sold as 4X.

Or maybe they have had time to improve CD-Burners that they
can burn older disks faster.

Or they turned out to be only reliable at 4X on all
burners even tho some could burn them at 24X.
