Hey everyone.
I bought a spindle of Memorex DVD+Rs. They turned out to be Ricohs

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.


#3

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


#5

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)
