This is a set of 5 Victor DVD-R DL (dual-layer, 215 minutes) discs for recording. Purchased at Yamada Denki on December 21st. I am selling these because I inserted a few into my home recorder to check compatibility, but none were recognized. Since I've lost track of which discs were inserted, I am selling them with the understanding that **"all discs have been inserted into a drive once and have had a recognition error."** Regarding recording: None of the discs have been recorded on, as the device displayed "cannot read" and no writing (recording) process was performed. 【Please Note】 I tested these with an old Sony recorder from over 10 years ago, which is why they were not recognized. However, they should work without issue in newer models or computer drives. Please purchase only if you understand that all discs have been opened and inserted once. The case has initial scratches.
