cutter together in sufficiently close contact u201c speed u201d is the rate at which the cutter is rotating the cutter typically is operated at about 10 000 30 000 rpm which is a relatively high speed that high speed cutter rotation is provided by a motor such a speed translates into a certain number of cutting surface feet per minute u201c feed u201d is the rate at which the disk surface passes by the cutter it will further be appreciated that the cutter is rotating so as to help the disk to rotate the cutter rotation augments the disk rotation such that a reduced amount of force is required by the roller motor driving the disk at the high speed motorized operation of the cutter disk declassification is accomplished in as little as about 3 10 seconds in a preferred embodiment the motor for driving the cutter may be run on a timing cycle the timing cycle may be initiated by a microswitch 7 as shown in fig4 which may be triggered by the to be processed disk in the declassification the cutter must be positioned so as to come in contact with the disk surface so as referring to fig1 to mechanically remove the shiny top surface 1 c and data area 1 d and separate them from the inserted disk 1 being processed the cutter is disposed in relation to the disk so that the disk center ring 1 b is not removed the cutting operation comprises the application of the patterned cutter that is rotating to the data surface of a rotating disk during the cutting operation one by product is dust that is.
