Title: Dropout detection circuit
Inventor: URANO MASAYUKI
IPC: G11B20/18
Filed: 1991-03-22
Abstract: PURPOSE:To surely detect the defective part of a magnetic recording medium. CONSTITUTION:A replayed signal from a magnetic disk 1 is fed to an AGC circuit 4; an output signal Sa from the AGC circuit 4 is fed to an envelope detection circuit 7 and a peak hold circuit 9. An output Sb from the detection circuit 9 and a voltage-divided output (a reference signal) Sc are fed to a comparator 8. At the low-level part (including a part which the AGC can not follow and whose cycle is short) of the replayed signal Sa, the level of the output Sb from the detection circuit 7 is lowered and becomes smaller than the level of the voltage-divided output Sc. At the low-level part of the replayed signal, an output Sd from the comparator 8 is set to 'H'. Thereby, the low-level part (dropout) of the replayed signal can be detected surely. When the signal Sd is set to 'H', a gate 5 is closed, and its output data DATA' is surely different from a recorded data. As a result, an error is caused, and the defective part of the disk 1 can be detected surely by using a controller 12.

Abstract: PURPOSE:To detect a rotation angle with high resolving power with use of a compact and light-weight apparatus by obtaining the rotation angle of a disc through detection of an angle of diffraction of light projected to the disc. CONSTITUTION:A light source 1 is placed above a disc 10. The light C from the light source 1 is projected at right angles to a part where slits SR and SC are formed in the disc 10. An angle of diffraction theta of the light incident upon the diffraction slit pattern is expressed by sin theta=hlambda/d wherein (h) is an order of diffraction 0, + or -1,+ or -2..., lambda is the wavelength of the incident light, and (d) is the pitch of slits. When the pitch (d) is changed, the angle of diffraction is accordingly changed. If the circumferential slit SC and the diametrical slit SR respectively having pitches dtheta1, dtheta2 are formed on the disc 10 to satisfy a specific condition, the combined diffraction light draws a circle as indicated by a chain line B. Since the rotation angle of the disc 10 corresponds to the diffraction light with 1:1, if the position of the diffraction light is detected, the rotation angle of the disc 10 can be obtained.
