Well the manufacturer is Moser Baer India Limited, as you can read from the media code I posted earlier. But it could be that the ones you have seen, could be another manufacturer. The only way to find this out is to buy them and have a look at the media code for yourself.
BTW: Please keep in mind that “we” are not some kind of support line, and that you need to have an answer within some hrs. We are all volunteers and most of us have other things to do instead of hanging out here 24 hrs a day.
Anyways I made a test disc form the TDK’s I got, burned at 52X with Liteon LTR-52327S using firmware QS0E. As you can see from the KPROBE scan, the scan are OK.
