A MEMS package has a MEMS chip, and a package substrate which the MEMS chip is adhered. The MEMS chip has an element substrate which a movable element is formed. The MEMS package has a particle filter formed on the package substrate or the MEMS chip. The particle filter has a pierced-structure, which plural through holes are formed on a base surface by a regular arrangement. Further, in the particle filter, a plane-opening rate is set at least 45%, and a thickness-opening rate is set at least 50%.

A bar mask for row bar processing includes at least a slider cover and at least a groove cover arranged adjacent to the slider cover. The groove cover is transparent, and the slider cover is opaque. The slider cover has two extending portions and an ABS portion arranged therebetween with some transparent patterns formed on the ABS portion. The ABS portion covers a single row bar, and the two extending portions each cover a row bar adjacent to the single row bar.

A thermally assisted magnetic write head includes a waveguide having a first end surface included in an air bearing surface; a magnetic pole having a second end surface included in the air bearing surface; a plasmon generator having a third end surface included in the air bearing surface; a first protective film directly covering a part of the second end surface of the magnetic pole at least; and a second protective film directly covering the first end surface of the waveguide and the third end surface of the plasmon generator. The configuration can reduce recording density and improve thermal stability, furthermore increase the producing yield.
