MFSL "ULTRADISC CD-R"

The tests .Scroll down for the ATIP info and the link to C1/C2 scans . It was not without certain excitement that I started the test. Not every day you get to burn $3 CD-Rs! ^_^ The first burn (at 8x) somewhat damped my enthusiasm: a coaster. The audio CD the image I tried burning of first was 15 seconds (!) longer than the Ultradisc's rated capacity. Even though PTP reported no errors during the burn itself, scans revealed a monstrous C2/CU surge at the very end. So the only finding the first round provided was that overburning (however slight) is not recommended with this CD-R. Stay under 74 min/650 MB to be safe. Subsequent burns were done with another, a bit shorter CD-DA image. Another puzzling annoyance popped up: sporadic C2 errors. I couldn't believe that such expensive media would burn with C2 s at 8x with a Plextor Premium. Into the DVD burner (PX-712A) it went then - and no C2 s! Upon a closer examination I noticed that the Premium was setting max read speed 10-24x CAV, while the PX-712A limited it to 8x which is apparently more appropriate for this media. When reloaded into the Premium and scanned at 8x, the C2 s were gone. And the C1 levels looked very nice as well. Burning at 4x lowered them some more, but they still remained a couple times higher than with Maxell CD-R Pro (rebranded Taiyo Yuden with extra scratch protection), my favorite. Since neither of my burners offers 12x that MFSL sez is Ultradisc's max recording speed, I gambled with 16x. This time, the burn aborted near the end with a write error 052C00 (ILLEGAL REQUEST: COMMAND SEQUENCE ERROR, according to PTP's help file).The conclusion . Pros: -low error levels -secure disc locking hub -spiffy looking disc and packaging <- see the Uploads section Cons: -C1 counts higher than with Taiyo Yuden -extravagant price -low burning speed limit -zero overburnability ATIP courtesy of Nero CD/DVD Speed v3.16:Manufacturer : Mitsui Code : 97m27s55f Disc Type : CD-R Usage : Audio Recording Layer : Dye Type 5: Short Strategy (Phthalocyanine) Recording Speed : n/a Capacity : 74:05.10 651 MB Additional Capacity : n/a Overburn Capacity : not tested ATIP courtesy of SmartBurn v3.1.8: Drive Type = CD-RW Disc Type = CDR Material = Phthalocyanine Lead In = 97:27:55 Lead Out = 74:05:10 Nominal Capacity = 650.85MB Manufacturer Maybe = Mitsui Chemicals, Inc.
