Abstract
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.
