ABSTRACT:
A floppy disk drive having a driving section provided with a spindle motor and a linear pulse motor includes a primary rail member (7) which determines a direction of movement of a reciprocating moving member (13) of the linear pulse motor and which has a plurality of V-shaped reference point cut-outs (8a, 8b) which serve as guides for reference pins (17, 18) of a jig. The spindle motor and the linear pulse motor are carried by a motor base (3) which has a plurality of holes (4a, 4b) for receiving the reference pins (17, 18). These pins are long enough to extend into the cut-outs. The holes (4a, 4b) have inner diameters which are larger than the outer diameters of the reference pins for enabling the motor base to be moved and adjusted. The arrangement enables an assembly of a floppy disk drive with high precision.
