1. A method of recording information signals on an information-signal recording medium having first and second areas, comprising the steps of:

  • storing into a first buffer memory a first information signal inputted at a first transfer rate;

    storing into a second buffer memory a second information signal inputted at a second transfer rate;

    reading out the first and second information signals from the first and second buffer memories on a time sharing basis;

    recording via a head the first and second information signals, which have been read out from the first and second buffer memories, on the first and second areas of the information-signal recording medium respectively on a time sharing basis at a third transfer rate higher than the first and second transfer rates, the head being movable relative to the information-signal recording medium; and

    deciding amounts of the first and second information signals read out from the first and second buffer memories for every read-out on the basis of (1) a time taken by the head to move from a point on the information-signal recording medium to a next point thereon, (2) the first transfer rate, (3) the second transfer rate, and (4) the third transfer rate to control a continuity in the time-sharing-based recording between the information-signal recording medium and the first and second buffer memories via the head.
