Abstract: PURPOSE:To prevent a counterfeit, etc. of a magnetic card, etc. by means of reproduction, by laminating in order a high coercive force magnetic layer, a high magnetic permeability magnetic layer and a low coercive force magnetic layer, on a base body, and recording an optional signal and a regular signal in the high coercive force magnetic layer and the low coercive force magnetic layer, respectively. CONSTITUTION:A high coercive force magnetic layer 2, a high magnetic permeability magnetic layer 3 and a low coercive force magnetic layer 4 are formed in order on a base body 1. Subsequently, a protective layer 5 is applied on the layer 4 and a magnetic  card, etc. are manufactured. An optional signal is recorded in the magnetic layer 2, and after that, a regular data is recorded in the magnetic layer 4. It is recorded in the layer 4 without exerting influence on magnetization of a signal of the magnetic layer 2, by making a proper recording current flow to the magnetic head. When reproducing this tape, a signal of the layer is shielded by the magnetic layer 3, is not outputted, and only the layer 4 is reproduced. When reproducing this card by means of contact magnetic transfer magnetic field, its magnetic shielding effect is lost, and the regular signal and the optional signal are recorded, therefore, it is easily detected to be a reproduction.

Title: Optical modulator control circuit
Inventor: AIZAWA SHIGEKI
IPC: G02F1/01
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To control the bias voltage of an optical modulator without being affected by an intensity-modulated component having a mean value of the finite band of an input signal and the finite band of the optical modulator. SOLUTION: A low-frequency signal outputted from a low-frequency generating means 11 is superposed on the bias voltage of an MZ type external modulator 32 through an adding means 13. The output light signal of the MZ type external modulator 32 is converted by a photoelectric converting means 13 into an electric signal. A DC and low-frequency removing means 14 removes a DC component and the low-frequency component of a low-frequency signal from this electric signal to detect only the amplitude-modulated signal component of the low-frequency signal. An envelope detecting means 15 detects the envelope of the output signal of the DC and low-frequency removing means 14. A synchronous detecting means 16 compares the phase of the output signal of the envelope detecting means 15 with that of the low-frequency signal.  An integrating means 17 integrates the output signal of the synchronous detecting means 16 and corrects a bias voltage applied to the MZ external modulator 32 through an adding means 12.
