To obtain a recording and reproducing device capable of suppressing vibration and displacement.

Pairs of magnetic members 13-1, 13-2 and 14-1, 14-2 are provided at carrying mechanism part 1 for mounting a recording medium so that the same poles face each other via a clearance 7 tilting toward a recording medium rotary shaft and a reading mechanism part 2 fitted to the part 1 via a vibration isolating mechanism part not shown in the figure for writing and reading information. Thus, it is possible to suppress the vibration and displacement of the part 2 in a direction within the surface of the recording medium mounted on the part 1 to be rotated by a spindle motor part 4 and in the direction of the rotary shaft of the recording medium orthogonal to it.
