I later bought another spindle of Memorex DVD+Rs and those turned out to be CMC Magnetics.

CMC Magnetics DVD+R’s have a much worse burn results (about 120PI/5PO) vs Ricohs (4PI/.03PO).
Is there a way I can make sure that the next spindle I buy actually is made by a specific company, Ricoh in this case? Is there a brand that uses Ricoh exclusively?

Thanks everyone

memorex spindles with grey bottoms are ricoh-R01 memorex with black bottoms that is shiny are cmc mag.

Thanks.

Are you sure it’s not the other way around? My last spindle had grey bottom and those were CMC Magnetics CDs…and the first spindle I had with black shiny bottom were Ricohs…

I’m sure every grey I have ever had was ricohR01 and every black was cmc mag, now I live in Southern california USA. If that makes a difference.

you said cds im talking about DVD+R 4x disks. And I have bought 4 spindles at least and they all were ricohR01 if i got grey bottoms

yeah mine are the same way-gray had cmc, black had ricoh’s. i’m in nc

Memorex vendors have changed packaging since the “grey-bottomed” 25pak spindles.
(“gray bottoms” still appear on store shelves, but probably older stock)

25paks

  • “gray” = Ricoh R01 - (Jan 04)
  • “dull black” = CMCMAG F01 - (Feb 04)
  • “shiny black” = Ricoh R01 - (May 04)

50paks

  • “gray” = Ricoh R01 - (Jan 04)
  • “shiny or dull black” - (not purchased, therefore, don’t know)

100paks

  • “dull black”/Printable version = Ricoh R01 - (June 04)
