PC World seem to pick up whatever they can from wherever they can. I've
noticed a colour change half way down a stack of 100. The first 50
discs gave a signal around 80% of that a pressing, the other half of the
stack gave less than 45% with a once-per-revolution dip in output[1].
Beware the ones branded "Packard-Bell", they are the same as thePCWs on
a stick but just labelled with a brand name and far more expensive.
Many well-respected brand names were giving low output about six months
ago and caused problems when they reached my customers. I switched to
HHB audio archival-quality blanks and have only had one dud in many
hundreds (and that was visibly dud, before I even recorded it).
[1] I made a meter to show signal strength from a cheap player and set
it up so that a pressing reads 100%.
HHBs read around 75-85%.
Many of the 'high street' brands were around 65-70% until last year,
then they dropped to 45-55%
Some PC World discs swung violently up and down around 30-45%
As a guide, I reject anything which drops below 50%.
