You never know, unfortunately, exactly what is in such spindles splashing around, Platinum is not itself blanks ago. , According to tests in the c't Ricoh allowed no goof at 8x as other manufacturers, unfortunately I can not myself reliable PI / PO values provide since I have no Plextor burner 712. DVD Identifier announces the following: -------------------------------------------------- ------------------------ Unique Disc Identifier: [DVD + R: RICOHJPN-R02-003] -------------------------------------------------- ------------------------ Disc Type: [DVD + R] Manufacturer ID: [RICOHJPN] Manufacturer Name: [Ricoh Company Ltd.] Media Type ID: [R02] Product Revision: [003] Disc Application Code: [General Purpose] Recording Speeds: [1x, 2.4x, 4x, 6x-8x] Blank Disc Capacity: [2,295,104 Sectors = 4,482.6MB = 4.38GB (4.70GB)] -------------------------------------------------- ------------------------
The Platinum 4x blanks (DVD + R: RICOHJPN-R01-002) which I have burned a year ago are still perfectly in highest speed read, I assume that this minimum are as good. From me there is a clear recommendation, find these discs are just as good as Verbatim or Taio Yuden, and the price is right.
