I own the CD Recorder CDR 770 by Philips. He reads everything and burn CDRs and CDRW. I have committed myself to CDRs and have been "FUJI CD-R PRO for Audio" on or before "FUJIFILM AUDIO CD-R" used for this purpose. However, the latter tend to 3 - 6 years to discolor and include sources of error, so that reproduction is no longer carried out properly. Now I have the CDRs of TDK, who want to use "CD-R Audio". The first CDR was recorded incorrectly. The second CDR was terminated after 8 of 21 titles. The third CDR has the "Philips CD Recorder CDR 770" can no longer read and reported "no disc". In short: I do not believe in "TDK CD-R Audio" blanks. The quality that promises the name TDK does not exist. TDK you can usually expect their blanks should be recognized on any CD-Recorder drive. Now I use the SONY CDR-blanks "CD-R Audio Premium"; 80s. No Problem; absolutely no problems. At TDK: 100 percent problems; hence no buy recommendation.
