摘要： A layered chip package includes a main body, and wiring that includes a plurality of wires disposed on a side surface of the main body. The main body includes: a main part including first and second layer portions; and a plurality of first and second terminals that are disposed on the top and bottom surfaces of the main part, respectively, and are electrically connected to the plurality of wires. Each layer portion includes a semiconductor chip having a first surface and a second surface opposite thereto, and includes a plurality of electrodes. The electrodes are disposed on a side of the semiconductor chip opposite to the second surface. The first and second layer portions are bonded to each other such that the respective second surfaces face each other. The first terminals are formed by using the electrodes of the first layer portion, and the second terminals are formed by using the electrodes of the second layer portion.

摘要： A thin-film magnetic head is constructed such that a main magnetic pole layer having a magnetic pole end face on a side of a medium-opposing surface opposing a recording medium, a write shield layer opposing the main magnetic pole layer on the medium-opposing surface side, a gap layer formed between the main magnetic pole layer and write shield layer, and a thin-film coil wound about the write shield layer or main magnetic pole layer are laminated on a substrate. This thin-film magnetic head has an equidistant two-stage structure in which a first turn part of a first conductor layer and a second turn part of a second conductor layer overlap vertically along the medium-opposing surface while having the same front distance from respective front side faces closer to the medium-opposing surface to the medium-opposing surface.
