ABSTRACT:
A recording system of the type wherein the information is recorded on a spiral track on a disk-shaped recording medium, which is rotated by a signal transducer which is moved radially with respect to the recording medium. Both the rotational speed or angular velocity of the recording medium and the velocity of the radial movement of the signal transducer are so controlled, in response to the radial position of the signal transducer or the time elapsed after the recording was started, that the relative velocity of the signal transducer with respect to the recording medium may be always maintained constant.
