ABSTRACT:
An information signal recording apparatus records an information signal on a disc having a rotation controlling signal recording track pre-recorded with a rotation controlling signal including a rotation mode discrimination signal which indicates whether the information signal recording disc is to be rotated in a constant angular velocity mode or in a constant linear velocity mode, a reproducing circuit for reproducing the rotation controlling signal recorded on the rotation controlling signal recording track, a motor for rotating the recording disc responsive to the reproduced rotation controlling signal, a mode discriminating circuit for discriminating whether the information signal recording disc is to be rotated in the constant angular velocity mode or in the constant linear velocity mode responsive to the rotation mode discrimination signal within the rotation controlling signal reproduced by the reproducing circuit, and a frequency modulator supplied with a luminance signal for producing a frequency modulated luminance signal. The frequency modulator changes a predetermined carrier reference frequency responsive to a discrimination result in the mode discriminating circuit.
