Abstract: A magnetic head includes: a pole layer including a track width defining portion and a wide portion; and an encasing layer disposed on a bottom forming layer and having a groove that accommodates the pole layer. The groove includes a first portion for accommodating at least part of the track width defining portion, and a second portion for accommodating at least part of the wide portion. A manufacturing method for the magnetic head includes: the step of etching a nonmagnetic layer that will become the encasing layer later, such that an initial groove including the first portion is formed in the nonmagnetic layer; the step of forming an initial groove mask covering the first portion; and a second etching step for etching the nonmagnetic layer so as to complete the groove. When the second etching step starts, a portion of the top surface of the bottom forming layer located in a region in which the second portion is to be formed is covered with the nonmagnetic layer or the initial groove mask.

Abstract: Systems and methods are disclosed herein for applying near-infrared optical energies and dosimetries to alter the bioenergetic steady-state trans-membrane and mitochondrial potentials (??-steady) of all irradiated cells through an optical depolarization effect. This depolarization causes a concomitant decrease in the absolute value of the trans-membrane potentials ?? of the irradiated mitochondrial and plasma membranes. Many cellular anabolic reactions and drug-resistance mechanisms can be rendered less functional and/or mitigated by a decrease in a membrane potential ??, the affiliated weakening of the proton motive force ?p, and the associated lowered phosphorylation potential ?Gp. Within the area of irradiation exposure, the decrease in membrane potentials ?? will occur in bacterial, fungal and mammalian cells in unison. This membrane depolarization provides the ability to potentiate antimicrobial, antifungal and/or antineoplastic drugs against only targeted undesirable cells.
