ATIP: 97m 27s 31f Disc Manufacturer: Pioneer Video Corp. Assumed Dye type: Cyanine (Type 1) Media type: CD-Recordable Recording Speeds: min. unknown - max. unknown nominal Capacity: 657.42MB (74m 50s 01f / LBA: 336601) I've used ten of them, in box package. I feel it is not very suitable for audio cds. At first I guess Prioneer is good at making Hifi, so I use it's cdr to test if it is also good at making audio cds. The audio cds play normally at begin, but after I play it for more times (about 10-20), my cd player cannot play some part of the tracks. But the player play other disc (eg prodisc) fine.
