Abstract
A disc recording apparatus which uses a disc recorded with address data beforehand and writes the TOC (information about recorded data) in a predetermined area on the disc. When a predetermined key is operated during recording, an address on the disc corresponding to an operation point of the key is written to the predetermined area as the TOC, generating positional information for data retrieval which substantially has no offset from a marker point on the disc. In reproduction, the TOC is read before starting reproduction, so that a desired marker point can be detected promptly based on the positional information of the TOC data.
