ABSTRACT:
A magnetic disc device for recording and reproducing data on a magnetic disc comprising a magnetic head for contacting the disc and for reading and writing data on the disc. A spindle for rotatably supporting the disc for contact with the head are provided. Further, the present invention includes a gimbal plate flexibly supporting the head for compensating for variations in the thickness of the disc and variations the surface level of the disc. The gimbal plate includes links for varying the elasticity of the gimbal plate between at least two directions. There are at least four links located in one direction for reducing stress on the gimbal plate and increasing the allowable degree of variation in elasticity between the two directions.
