Abstract
A floating magnetic head used in a hard disk drive has a substantially rectangular slider made of a non-magnetic material. The slider has rails mounted on a surface of the slider that is opposite to a magnetic recording medium to produce a floating force. A cut-out is formed in the slider, for example, at one corner of the slider for providing access for winding a coil and a bridge spans the cut-out portion. A head core having a read/write gap is bonded to an outer periphery of the slider adjacent the cut-out portion. In particular, a winding portion of the head core is bonded to the bridge spanning the cut-out portion for receiving a portion of a winding coil. Accordingly, if a large force acts on the head core during winding of the coil or mounting of the floating magnetic head to a suspension, the head core can withstand the force without incurring damage or adversely affecting its ability to function.
