Abstract

A fixed type multi-channel head device with a plurality of floating head sliders held thereby, is provided with a sheet of positioning spring member having a number of individual gimbal spring portions each integrally holding at the central part one floating head slider, a sheet of load spring member including a number of gimbal spring portions or cantilever type spring portions applying load from the rear sides of a plurality of sliders to said floating head sliders, respectively, and a plurality of pivots disposed between the pairs of spring portions of the positioning and load spring member, each separating one spring portion of the paired ones from the other spring. The positioning and the load spring members are superposed such that the tip of each pivot comes in contact with the central part of the rear surface of each floating head slider.
