PROBLEM TO BE SOLVED: To obtain a recording and reproducing apparatus where the free movement of its optical head mechanism part is restrained mechanically by utilizing an existing mode motor when the linear motor is not receiving electric power supply. SOLUTION: In the recording and reproducing apparatus which is equipped with an optical head mechanism part 6 for recording or reproducing information on a disk recording medium and a linear motor 14 which moves an optical head mechanism part 6 in the diameter direction of the disk recording medium and in which the optical head mechanism part 6 moves freely when no energy is supplied to the linear motor 14, a projecting piece 4 is provided on the arm lever integrally interlocked with a mode lever 28 which is slid with a mode motor 31 which constitutes the driving source for performing a mode operation of the recording and reproducing apparatus so that, when power is not supplied to the linear motor 14, the projecting piece 40 is engaged with a recessed part 41 provided on an optical head mechanism part 6 and the free movement of the optical head mechanism part 6 is restrained mechanically.
