ABSTRACT:
An information recording and reproducing apparatus of the hard disk type comprises a motor for rotatably driving hard disks secured to a driving hub attached to the driving shaft thereof, a pivot assembly having a pivot shaft supporting a swing arm for swing motion thereon, magnetic heads attached to the free end of the swing arm so as to be located opposite to the surfaces of the hard disks, respectively. The lower bearing among the bearings rotatably supporting the driving shaft of the motor and the lower bearing among the bearings rotatably supporting the pivot shaft of the pivot assembly are always urged in the same direction by bearing biasing means, respectively. When gaps are formed between the lower bearing of the motor and the inner wall of the bearing housing and between the lower bearing of the pivot assembly and the inner surface of a hole receiving the pivot assembly due to the difference between the lower bearings and the surrounding parts, the driving shaft of the motor and the pivot shaft are tilted in the same direction practically by the same angle, so that the off-track of the magnetic heads is limited to the lease extent, and hence the deterioration of the recording and reproducing performance of the apparatus due to thermal expansion of the components is prevented.
