Title: Magneto-optical combined head
Inventor: MIYAKE TOMOYUKI
IPC: G11B7/1372
Filed: 1989-03-31
Abstract: PURPOSE:To allow the use of the recording medium having a large coercive force and the execution of a high-density recording by providing the optical waveguide of an optical head on the surface of the magnetic head to face the recording medium, and irradiating a part of the recording medium where the magnetic field is impressed from the magnetic head with a laser light. CONSTITUTION:The temp. in the part of the recording medium 12 irradiated with laser light (b) rises and the coercive force decreases, when the laser light emitted by a laser light generating means 11 progresses in the waveguide layer 7 of the optical waveguide 5 and is guided by optical system parts 9, 10 of the optical waveguide 5 and the part of the recording medium 12 where the magnetic field from the magnetic head 2 is impressed is irradiated with the laser light (b). The recording is executed in this state by the magnetic field (m) impressed from the magnetic head 2. The magnetic recording is executed in the state of lowering the coercive force of the recording medium 12 in such a manner. The recording at the high density is thus executed by using the recording medium having the large coercive force. Since the magnetic recording on the recording medium is executed in the state of the lowered coercive force, there is no need for bringing the magnetic head too much to the recording medium and the influence of dust between the recording medium and the magneto-optical combined head and the possibility of a head crash are decreased.

IPC: G06K17/00
Filed: 1985-04-19
Abstract: PURPOSE:To keep the high accuracy of data to be written by comparing the level inverting interval of read signals with the standard value to check the interval is within a prescribed allowable error or not and setting the allowable error smaller in a reading check mode after writing of data for replacement, etc. than a reading mode of data on a recording medium which are already written on the outside. CONSTITUTION:A counter 7 functions to ignore the speed variation produced when a card 1 is rushed into a magnetic head. In other words, the counter 7 is set when a prescribed number of pulse signals S6 are supplied to the counter 7. Then the output of the counter 7 is set at a high level and sent to the next stage in the form of a check start signal S7. Therefore, the checking result of signals read by a head 2 is not transmitted to the next stage as long as the signal S7 is kept at a low level. That is, the period when the signal S7 is kept at a low level is set in a period during which the speed variation is produced by the inrush of the card 1 into the head and actually obtained from an experiment.
