The answer PROBABLY is: your Marantz recorders need service (maybe you can get a group rate :-) ) Same thing happened to my TASCAM CD-RW700, right after thw warranty expired.
Problems with CDR-audio blanks?
I own two Marantz DR-700 CDR audio recorders. I've started to have a problem with both machines ( which makes me doubt it's the machines) - the initial stage of recording a one time use CD audio blank involves the machines scanning the disc's looking for errors and to make sure the disc's are registered as "audio" recordable CD's - this process is called OPC - what's happening is that entire batches of CDR-audio blankks are failing the OPC - they can't be recorded on.
I have used hundrerds of Memorex blanks - these quit working in my machines , just tried 5 Imations - no luck - went thru two 50 pack spindles of Maxell's - no luck , TDK's work fine ???? To clarify - once recorded - even older recorded disc's PLAY fine - it's recent purchases that don't seem to be recordable.
Anyone else expereinced this problem? The answer is ???
