Abstract
According to the invention, there is provided a laminar magnetic head having bonding pads formed in so many layers and laminated with laminar component devices and circuits so that the surface areas of the bonding pads can be significantly enlarged without altering the arrangement of the lower layers of devices and circuits. Such a design ensures miniaturization and realization of a complex structure of a magnetic head as well as an enhancement of the workability and strength of the lead wires of the head for connection with by simply altering the patter of arrangement of the bonding pads and without significantly altering the production process that can involve a rise of manufacturing cost.
