A magnetic head supporting member, on which is mounted a magnetic head for recording and/or reproducing of information on a magnetic disc, is mounted on a magnetic head driving motor through a temperature-compensating member. Owing to the above construction, since each of the length, shape and thermal expansion coefficient of the temperature-compensating member has considerable flexibility in selection, it is possible to obtain an excellent magnetic disc unit in which desired temperature-compensating conditions can be easily obtained without any loss of flexibility in designing of the material, position and length of each constituent member of the magnetic disc unit.

A magnetic disc unit comprising: means for driving a magnetic disc; magnetic head means including a first magnetic head and a second magnetic head for recording and/or reproducing information on opposite surfaces of said magnetic disc; magnetic head driving means for transferring said first and second magnetic heads to predetermined position on said magnetic disc; a temperature-compensating member for compensating relative misalignment between said first and second magnetic heads due to a variation in temperature; a first magnetic head supporting member supporting said first magnetic head and being mounted on said magnetic head driving means via said temperature-compensating member; and a second magnetic head supporting member supporting said second magnetic head and being mounted on said magnetic head driving means via said temperature-compensating member, wherein said first and second magnetic head supporting members are mounted on said temperature-compensating member at positions separated from each other by a distance corresponding to the difference in the thermal expansion coefficients of said first and second magnetic head supporting members.
