Abstract: An apparatus is disclosed for left/right determination of the arm part of a pig carcass before it is deboned. A plurality of clampers move around on an endless track. At a suspension station, a work is suspended from each clamper. There are left/right and front/back determination stations where it is determined whether a left-side or right side, and a front-side portion or back-side portion is facing a side irradiated by X-rays. Based on results of the determinations, posture of the work is corrected by a clamper rotating device. At an X-ray imaging station, it is controlled so that the front-side portion of the work faces the side irradiated by the X-rays and a longer side faces a movement direction of the endless track. An X-ray image of the work is obtained to determine a target coordinate of a bone-part surface required for incision making and deboning processes.

The magnetic recording medium includes a substrate, a recording layer formed in a predetermined concavo-convex pattern over the substrate, convex portions of the concavo-convex pattern serving as recording elements; and a filler portion filling a concave portion between the recording elements. The filler portion comprises a metal-based main filler material and oxygen. Oxygen is unevenly distributed in the filler portion so that the ratio of the number of oxygen atoms to the total of the number of atoms of the main filler material and the number of oxygen atoms is greater in an upper surface portion of the filler portion than in a lower portion of the filler portion.
