Title: Magnetooptic recording and regenerating apparatus
Inventor: MATSUMURA SUSUMU
IPC: G11B5/02
Filed: 1990-11-22
Abstract: PURPOSE:To make it possible to perform high-density recording by applying an external magnetic field in the constant direction in the same direction as the magnetizing direction with in the data magnetic domain, which is recorded on a data track, on a recording medium when the data are regenerated. CONSTITUTION:A magnetic head 1 applies a bias magnetic field which is modulated in response to recorded data in recording with a driving circuit. At the time of regeneration, a constant magnetic field H which is weaker than the bias magnetic field is applied in the constant direction. The regeneration of the data is performed under the state wherein the optical intensity of a semiconductor laser is lowered to regenerating power and the magnetic field H in the constant direction is applied on a magnetooptic disk 2 from the magnetic head 1. Under this state, regenerating luminous flux is emitted on the data track as a spot from the semiconductor laser 7. Therefore, the regenerating magnetic field H applied from the magnetic head 1 is overlapped with the magnetization in a data magnetic domain and intensified to each other. Therefore, the magnetic field acts so as to widen the magnitude of the data magnetization. Thus, the ratio of the occuping area of the magnetic domain with respect to the optical spot is increased, the S/N of the regenerated signal can be improved, the limit of the regenerating density can be allevaited and the recording density can be further increased.

IPC: H03K19/0185
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by providing a bias means to allow a pull-down side MOS transistor to be made to operate nearby a threshold from among voltage dividing MOS transistors inserted between a boosting potential and the ground potential. SOLUTION: A boosting potential is pulled down, and the potential of a signal detection terminal A is obtained by making a through-current flow from a boosting potential applied point C to the ground potential. A PMOS transistor 2 for controlling the through-current is operated nearby a threshold, and the through-current is suppressed to a minimum. When the boosting potential is normal, the gate electrode potential of the PMOS transistor 2 is slightly above the threshold voltage at its absolute value. Thus, the PMOS transistor 2 is in a conducting sate. When the boosting potential becomes lower than normal, the transistor is in a non-conducting state. Such a control operation is executed by a self-bias part 3 which is constituted of a MOS transistor 31 and a PMOS transistor 32.
