    摘要： A magnetic head comprises a head base (56), and a pair of magnetic head chips (57, 58) of different azimuth angles (.theta..sub.1, .theta..sub.2) disposed on the head base (56). The pair of magnetic head chips (57, 58) are disposed in a stepped arrangement with respect to the direction of arrangement of tracks on a magnetic recording medium with a step (DA) substantially equal to the pitch (P) of tracks on the magnetic recording medium. The gap distance (GL) between the magnetic gaps of the magnetic head chips (57, 58) is shorter than the sum of the step (D) between adjacent tracks and the length (L) of interblock gap regions between video signal regions and audio signal regions arranged along the direction of the movement of the magnetic head. The magnetic head permits satisfactory audio signal after-recording and extended recording and reproducing of digital video signals on the magnetic recording medium even if the magnetic recording medium is a narrow magnetic tape of 8 mm or less in width.

    摘要： Thin film type magnetic transducer head is disclosed in which a track width recorded on a magnetic recording medium is determined by a thickness of thin film magnetic core halves formed on a non-magnetic substrate. The head has a rear core portion having a larger thickness than the track width forming portion of the head facing to the travelling magnetic recording medium, and a coil wound around the rear core portion. The coil comprises first coil portions underlying the rear core portion and second coil portions overlying the rear core portion and third coil portions connecting the first and the second core portions. The head is manufactured by thin film forming technique in combination with photolithography.

    摘要： In a magnetic sensor having soft magnetic metallic elements disposed in opposite sides of a bridge circuit for sensing an external magnetic field by using a phenomenon where a skin depth of the soft magnetic metallic elements changes in dependence on a strength of the external magnetic field, each of the soft magnetic metallic elements is formed in a zigzag shape having parallel sections extending in a direction of the external magnetic field. The soft magnetic metallic element may have a multi-layer structure where soft magnetic layers are laminated with a non-magnetic insulator layer interposed therebetween.
