Title: Magnetic head structure for magneto-optical recording device
Inventor: ISHII KAZUNORI
IPC: G11B11/10
Filed: 1991-06-04
Abstract: PURPOSE:To invert a magnetic field at high speed and to make the magnetic head suitable for recording high frequency information by providing a magnetic coil flatly and helically winding a lead wire on a base composed of a magnetic substance for the magnetic head. CONSTITUTION:For the magnetic head, a base 1 composed of the magnetic substance is arranged at the part of a slider S. The slider S is composed of a non-magnetic hard material and a magnetic coil 2 is constituted by helically winding the lead wire on the base 1 on a plane back rather than the air bearing surface of the slider S. Then, a current flowing to the coil 2 generates the modulated magnetic field on the base 1. Further, the surface of the base 1 is covered with resin or low fusing point glass material 3 so as to be equal with the surface and the magnetic coil 2 is embedded under the base. Thus, since the magnetic field is generated at a position extremely close to the recording plane of a counter magneto-optical recording medium, the magnetic field can be inverted at high speed.

Abstract: PURPOSE:To control whether a magnetic tape in a pause state is run or held as it is, according to the presence of a tape-end detection output when the magnetic tape is in stop mode and a run mode and a mode input right before the tape is stopped. CONSTITUTION:Sheets of metallic foil 12 and 13 fitted to the stating terminal and ending terminal of a magnetic tape 11 are detected by tape starting-terminal and ending-terminal detection coils 16 and 17 to stop an oscillating circuit 31, thus performing the detection by a tape end detecting circuit 32. In a memory 36, whether a mode right before stopping operation is a forward run or reverse run mode is stored, and when the magnetic tape is run in this state, a current- mode detecting circuit 20 discriminates between the forward run mode and reverse run mode. When a mode input indicates the forward run mode and the circuit 32 generates an output, a discriminating circuit 34 refers to the output of a detecting circuit 35 for a mode right before the stop operation and if the forward run mode is known, it is judged to be the output of the detection coil 17, stopping the tape 11 by a stopping circuit 24. Namely, this control uses the tape- end detection output, a run mode right before the stop operation and the mode input.
