Abstract
The disclosure is directed to a method of preparing a recording of a computer program whereby the recording is usable on one and only one preselected computer hardware system. The recording system of the invention comprises a two phase recording process wherein phase one of the system is utilized to record on a permanent memory element all of the basic information to be stored thereon, including a preselected application program for a computer system, as well as additional information containing instructions to make the first computer used in connection with recording a component to complete phase two of the recording process. The second phase recording aspects of the invention complete the recording of each element in an individual recording step on the selected first used computer in a manner to link the operability of the individual recording to the particular, selected first-to-be-used computer machine.
