Mitsubishi Multisped Cd Media

i just came across some mitsubishi multispeed cdrs and i was wondering if someone could tell me about their reputation...the cover says they are made of phthalo cyanine and are made in japan. i wanna know who the manufacturer is [CMC, etc], and well, your personla experience if nay.

also, are azo dyes better then this phthalo thingy?

Mitsubishi are a realitivly reptuable company i wouldnt wory about stuff from them, just be carfull about buying mass quantities of disks aka 100 for $10 > £5
