PURPOSE:To obtain a reproduced image with high resolution, by providing a means which displaces an individual recording and reproducing element by an actuator. CONSTITUTION:On a cylindrical rotary magnetic recording medium D, plural pieces of recording and reproducing elements Hr, Hg, and Hb are mounted at the actuators ACTr, ACTg, and ACTb provided in an individual tracking control system via a supporting member, and the actuators ACTr, ACTg, and ACTb are fixed at a common carrier FA, and a guide bar 5 is inserted to the carrier FA, and also, a feed screw 4 driven rotatably by a carrying motor Mf is engaged with the carrier. In such way, an operation to displace the recording and reproducing element is performed until each recording and reproducing signal can trace on a recording mark where a signal mark identification signal San taken out from a recording signal reproduced respectively by the plural pieces of recording and reproducing elements, coincides with the information Sads of the position of the recording mark set at an operating part OP.
