ABSTRACT:
A disc control apparatus comprises a first register for storing a first track position which is presently traced, a second register for storing a second track position which is next to be traced, a first memory for storing a first rotating number of a disc under a seek operation, and a second memory for storing a second rotating number of the disc at a settling time. The first track position is an upper address signal for the first memory, and a lower address signal for the first memory is produced in accordance with a subtraction between the first and second track positions, so that the first memory is accessed at an address composed of the upper and lower addresses to produce the first rotating number signal. The second memory is accessed at an address determined solely by the first track position to produce the second rotating number signal. A signal obtained from the aforementioned subtraction, and the first and second rotating number signals are added to produce a head moving signal which indicates a head moving direction and a jumping track number. As a result, the head is controlled to move from the first track position to the second track position by a single seek operation.
