ABSTRACT:
An information-reading head having a structure comprising a floatable information-reading head, and a suspension comprising a load arm for supporting the information-reading head via a gimbal. The gimbal having a frame structure in a reversed trapezoidal shape constituted by an upper horizontal portion fixed to the load arm, a lower horizontal portion to which the information-reading head is fixed, and a front portion and a rear portion. At least one of the front and the rear portion being inclined, whereby the information-reading head is substantially prevented from pitching forward when coming into contact with a surface of an information-bearing mechanism. The suspension supports the information reading head such that a center of gravity of the information reading head is positioned between a center of support of the information-reading head by the suspension and a rear of the information-reading head.
