Hi all what is a test mould disc?
What kind of disc are we talking about?
I don't think its anything, when I Googled the term in quotes only your post showed up as a result.
I work in the DVD industry performing copy-protection. A Test Mold for DVD is when a small sampling (maybe 100 discs) are pressed for test purposes. We use the test molds to test the compatabilityof our copy protection with up to 125 different players. These represent the major portion of the most popular DVD drives on the market with identical or similar chip sets.
I would imagine in record pressing the purpose is similar, but moreso to check the quality prior to replication. I would consider record test molds as excellent quality, since they're pressed from a new master and has the best possible grove condition.
It would be similar in DVD production since a new master has the best pressing surface allowing the best possible formation of pits minimizing jitter.
Spot on, usualyl white label and very rare!
Can sell for quite a bit depending on what is on them...
Especially with collectors, condition can vary as a lot of people have played them as normal
Never knew they did it for DVD's etc though, interesting post
For DVDs it's done more for testing purposes. For records it was for quality and marketing. Finding a first run LP is rare, let alone getting one. Since the master image for DVD is software instead of mechanically cut, getting first quality pressing is much less difficult than with vinyl.
Why, do you want to buy one? reeel cheap mister...
(just saw your thread in feedback )
I was offered a few of them (via a dodgy PM) from a guy in eastern europe in exchange for a blu ray that i had for sale in the classifieds.
I wish i'd taken them now just out of curiousity
