Title: Constant current circuit
Inventor: KIMURA KEIJI
IPC: G05F3/22
Filed: 1980-05-12
Abstract: PURPOSE:To set the value of constant current to a very small value, by controlling the collector current with a current flowing to a diode externally via the connection point between one of transistors with common base for the pair and a diode. CONSTITUTION:The bases of pair transistors (Tr) Q1, Q2 are connected commonly and a current is applied to the collector connected to the base of TrQ1, allowing to supply a prescribed voltage to the emitter of the TrQ1 against a ground potential. Further, the collector current of TrQ2 is controlled with a current fed to a diode Q4 externally via the connection point between the emitter of the TrQ2 and a diode Q4. Thus, the voltage drop of the diode Q4 is used for current compression at the constant current circuit and the voltage drop is adjusted with a current flowing to the diode Q4 externally, allowing to set the value of the constant current to a very small value.

Abstract: PROBLEM TO BE SOLVED: To easily and properly decide the kinds of both a reproduction-only optical disk and a recordable optical disk by deciding that an object optical disk is the reproduction-only optical disk when its value is smaller than a previously set specific reference value and the recordable optical disk when larger. SOLUTION: A disk kind decision means 13 is composed of a comparator 14 which compares the level signal of a normalized push-pull amplitude voltage inputted through an AD converter with a reference voltage V1 as the previously set specific reference value. This comparator 14 is used to compare the 1st normalized push-pull amplitude with the reference voltage V1 as the specific reference value for decision making and the kind of an optical disk is decided according to whether its output is at H or L level. It is decided that the optical disk is the recordable optical disk which is an R or RW disk when the output is at the H level or a ROM disk when at the L level.
