These are quite famous discs, seeing as Prodisc is one of the biggest manufacturers of CDRs in Taiwan, behind only CMC and Ritek, and, in my opinion, have always been of the highest quality. ATIP generally is: ATIP: 97m 32s 19f Disc Manufacturer: Prodisc Technology Inc. Reflective layer: Dye (Short strategy; e.g. Phthalocyanine) Media type: CD-Recordable Recording Speeds: min. unknown - max. unknown nominal Capacity: 702.83MB (79m 59s 74f / LBA: 359849) Those were both for my unbranded discs sold as Plajet and for my noname discs, I have tried no other brands but the quality should be the same. Great quality overall, and highly recommended. Should be really cheap, the only cheaper thing than them around here are Acer Silvers which are IMO not as good. I've had some problems (Slow reading on the end) with about 5 in a spindle of 100, but other discs, from the same or from different batches, haven't shown these problems. Very highly regarded.
