Title: Optical recording and reproducing device
Inventor: WATANABE JINKO
IPC: G11B11/105
Filed: 1987-11-30
Abstract: PURPOSE:To exactly detect drop-outs distributed in an adjacent band to an FM carrier frequency as well by detecting pulse-like noises out of a signal being reflected in reflectance ratio on a groove of a magneto-optical disk. CONSTITUTION:By adding up signals outputted from pin diodes 11 for detecting a signal of a magneto-optical pickup with an adder amplifying circuit 17, the signal reflected in reflectance ratio on the groove of the magneto-optical disk is obtained, and the pulse-like noises generating on this signal are detected, and moreover a criterion value of such a pulse-like noise is taken as (1+ or -alpha) times (provided that alpha=0.2-0.25) as much as the mean value of the reflectance ratio on the groove, so as to carry out the detection with a voltage comparator 19. By this method, small drop-outs distributed also in the vicinity of the FM carrier frequency can exactly be detected out, thus enabling the excellent correction of the drop-out.

Abstract: PURPOSE:To prevent the corrosion of a case, to eliminate charging in cases and to avoid the occurrence of electric accidents by using a solid polarizing electrode as a basic cell, and using a resin case for an outer packaging case. CONSTITUTION:As a basic cell 6, a cell wherein a polarizing electrode is a solid polarizing electrode is used. Since active carbon powder is sintered in this solid polarizing electrode, the contact amount the active powder particles is very excellent, and pressure to be applied on the basic cell 6 is largely decreased. Several pieces of ht basic cells 6 are laminated. An electrode plate 1 is applied on one surface, and an electrode plate 2 is applied on the other surface. An insulating plate 5 is provided between a lead-out terminal 1A (2A) and the side surface of the basic cell 6. Thus the contact with a current collector 11 having the different polarity is prevented. Such a device is packaged with resin cases 3 and 4 from both sides. The inside is tightly sealed by thermal welding. When the resin cases such as these are used as an outer package, the device is not subjected to corrosion even if electrolyte leaks from the basic cell 6. Since the cases have insulating property, the cases are not charged, and electric accidents do not occur between the device and peripheral apparatuses.
