Title: Method for recording optical information and information recording medium
Inventor: KANAMORI KATSUYUKI
IPC: G11B7/243
Filed: 1987-03-13
Abstract: PURPOSE:To enable readout with a commercially available CD player by rotating an information recording medium having a specified recording layer on the substrate at 1.2-1.4m/sec constant linear velocity and by radiating light on the recording layer to record a CD format signal by a bubble mode. CONSTITUTION:A recording layer of >=300Angstrom  thickness contg. 30-80wt.% indium and 70-20wt.% at least one kind of metallic compd. selected among metallic sulfide, fluoride and oxide is formed on a substrate with a chlorinate polyolefin layer in-between. While the resulting information recording medium is rotated at 1.2-1.4m/sec constant linear velocity, light is radiated on the recording layer to record a CD format signal by a bubble mode. Since the recording layer having the recorded CD format signal has high reflectance, the signal can be accurately read out with a commercially available CD player.

Filed: 1980-05-01
Abstract: PURPOSE:To prevent the deterioration of the cross modulation characteritics of an AM receiver in a detuning state, by providing a transistor which limits an input to a field effect transistor provided to the initial stage of a high frequency amplifying circuit. CONSTITUTION:Transistor TRQ2 is provided to limit an input to FETQ1 provided to the initial stage of high frequency amplifying circuit 1. Until the input level reaches desired S/N, this TRQ2 is held turned off because of the reverse bias characteristics of diode D and the input to FETQ1 is not limited. As the input level rises above the desired one, TRQ2 turns on-off in response to the control voltage of AGC circuit 6 varying suddenly. This on-off operation limits the input to FETQ1 according to the level. Thus, the deterioration of the cross modulation characteristics is prevented.
