A disk recording device of the invention has a detector for detecting the position of an optical head with respect to the radial direction of a disk, using an optical scale, and a position signal processing circuit for generating a position signal from the output signal from the detector. An output signal from the circuit is converted by a D/A converter into a voltage signal, which is supplied to a voltage controlled oscillator. The oscillator generates a frequency signal. The frequency signal is supplied to a page buffer storing video data and one input of an AND circuit. The other input of the AND circuit is connected to receive a video data from the page buffer. The AND circuit generates a logic product of the frequency signal and the video data, or a recording timing signal having a frequency which is proportional to the position of the head with respect to the radial direction of the disk.
