摘要： A narrow magnetic body 66 in which outward path and inward path recording magnetic head devices 1WF and 1WR, capable of recording at least data on a metal evaporated type magnetic tape 51 running in the outward and inward direction and vice versa along the longitudinal direction, comprise the operation magnetic gaps GF and GR with the asymmetric structure is located at the leading side of the metal evaporated type magnetic tape 51. With this arrangement, magnetic field influence exerted by the narrow magnetic body can be decreased, and difference produced between magnetic recording and reproducing characteristics when the metal evaporated type magnetic tape is transported in the outward direction and in the inward direction can be decreased. Also, deteriorations of characteristics deteriorated by off-track upon reproduction can be improved. Thus, when the recording magnetic heads with the operation magnetic gaps having the asymmetric structure are in use and the metal evaporated type magnetic tape is transported in the outward and inward direction and vice versa, difference produced between magnetic recording and reproducing characteristics when the metal evaporated type magnetic tape is transported in the outward and inward direction and vice versa can be decreased. Also, deteriorations of characteristics deteriorated by off-track upon reproduction can be improved.

摘要： A vibrating gyrosensor includes a support substrate on which a wiring pattern having lands is formed. A vibrating element is mounted on a surface of the support substrate. The vibrating element includes a base part having a mounting surface on which a number of terminals connectable to the lands is formed. A vibrator part integrally projects from a side of the base part and has a substrate-facing surface coplanar with the mounting surface of the base part. The vibrator part has a first electrode layer, a piezoelectric layer, and a second electrode layer which are laminated on the substrate-facing surface. The vibrator part vibrates when an AC signal is applied between the first and second electrode layers. The central electric field strength of the AC signal is set at a position shifting to the positive direction from the center of a hysteresis loop of the piezoelectric layer.
