The technology of using stationary MR heads was later further developed by [[OnStream]] for use as a data storage media for computers. MR heads are now also commonly used in [[hard disk drive|hard disks]], although hard disks now use the [[giant magnetoresistance]] variant, whereas DCCs used the earlier [[magnetoresistance#Anisotropic magnetoresistance (AMR)|anisotropic magnetoresistance]].<ref>[https://books.google.com/books?id=Iefd6kCbFxsC&dq=dcc+gmr&pg=PA110 Magnetic Multilayers and Giant Magnetoresistance - Uwe Hartmann, R.

A derivative technology developed originally for DCC is now being used for filtering beer. Silicon wafers with micrometer-scale holes are ideal for separating yeast particles from beer, as the beer flows through the silicon wafer leaving the yeast particles behind. This is desirable when the final beer is meant to be extremely clear. The manufacturing process for the filters was originally developed for the read/write heads of DCC decks.<ref>{{cite news |first=Barry |last=Fox |date=11 June 2004 |url=https://www.newscientist.com/article/dn6121-hi-fi-failure-helps-to-brighten-beer |title=Hi-fi failure helps to brighten beer |journal=New Scientist |access-date=2007-04-02}}</ref>
