ABSTRACT:
Digital computer data recorded in a spiral track on the surface of a disk using a laser recording head which moves radially across the disk as it revolves at a constant linear velocity. A system for controlling the disk velocity during the recording process includes a device for counting each convolution of the spiral and means for calculating the number of bits of information which should optimally be recorded in that convolution. A counter keeps track of the number of bits which are actually being recorded in that convolution. The calculated number of bits is compared with the number of bits actually recorded to produce a control signal for regulating the speed at which the disk revolves.
