Abstract

PURPOSE:To prevent damaged magnetic head chips, by avoiding the contact of the reader tape with the magnetic head chip, through the provision of the magnetic head movably toward radial direction of mounting. CONSTITUTION:The spring pressure of the plate spring 9 is weaker than the centrifugal force produced at the stationary revolution of the head disc and the position in radial direction of the stopper 5 is determined at a given location, then the magnetic head chip is projected by the size of P at normal revolution to enable recording and reproduction to the magnetic tape. Further, in threading the reader tape, or rewinding, control is made that the revolution is stopped or minimum revolution in which the magnetic head chip is drawn in from the drum is kept, then the contact between the magnetic head chip 1 and the reader tape can be avoided.
