Abstract: A mode processing circuit for a multiple operational mode electronic apparatus such as a video tape recorder includes a mode stack having a plurality of stages in which an input command signal is stored as an operational mode of the electronic apparatus. The operational mode supplied to the mode stack is sequentially stored and optimized, and the optimized operational mode is read out from the mode stack in sequential order and then executed after the transition of the operational mode has ended.

Abstract: PURPOSE:To form a C-MOS comparator circuit which provides a stable operation with a large gain though with limited number of elements, by using at least three sets of C-MOS. CONSTITUTION:Three sets of complementary type P-channel and N-channel MOS transistors (C-MOS) are provided in series between two power sources VDD and VSS and compose inverters 11-13 respectively. A reference voltage VRL is applied to gates of P-channel elements 11P and 13P of the inverters 11 and 13 while an input voltage Vin is applied to gates of the P-channel element 12P of the inverter 12 and the output voltage Vout is taken out at the connection mid-point between an N-channel element 13N and the element 13P of the inverter 13. When the ratio of the respective inverters is equal and VSS VRL. Thus, limited number of elements are enough with a larger gain and the stability of operation is already confirmed from the results of simulation.

Abstract: PURPOSE:To apparently eliminate a transition time by providing a transition vector table and making mode transition according to the transition vector table. CONSTITUTION:A mechanism controlling section 1 is provided with a loading motor 11 that makes loading and unloading of a tape, a control motor 12 that controls mode of a VTR (mechanism), and controller 2 is supplied to the controlling section 1 to make respective mode, and at the same time, signals indicating the state are supplied from the controlling section 1 to the controller 2. A mode transition table and a transition vector table are provided in the ROM of a microcomputer that constitutes the controller 2. When an operation key of a key inputting means 3 or an operation key of the controller of a remote- controller is depressed, this is processed by the controller 2, and the result of processing is supplied to the controlling section 1, and the controlling section 1 is controlled to attain a specified operation mode, and at the same time, the mode is displayed by a displaying means.

Abstract: PROBLEM TO BE SOLVED: To obtain a reproduced output in which crosstalk is small and whose level is sufficiently high even when magneto-optical recording area where embossed pits are formed and the area where the pits are not formed are made adjacent by making a magnitude of a phase difference to be generated by the double refraction of a substrate and the magnitude of a phase difference to be generated by the Kerr elliptic effect of a recording layer within specific ranges. SOLUTION: Recording layers are formed on a substrate on which embossed pits indicating information are formed and the layers are made to have a groove recording format. In intra-surface directions, a direction orthogonal to a recording track and a direction being along the recording track are respectively defined as an x direction and a y direction. When a phase difference to be generated by the double refraction of the substrate and a phase difference to be generated by the Kerr elliptic effect in the phase difference between the deflection component of the x direction and the deflection component of the y direction of the return light of the reproducing light reflected on the recording layer are respectively defined as ϕbr and ϕMO, these are made to satisfy -20 deg.C

Abstract: PROBLEM TO BE SOLVED: To enhance the recording density of a recording medium to have equal to or higher than a resolving power to be determined with the wavelength of reproducing light by impressing a magnetic field to a magnetic recording medium so that magnetization is directed in a fixed direction in the region of one part in the spot of reproducing light when an information signal is reproduced by irradiating the medium with the reproducing light. SOLUTION: When a magneto-optical disk is irradiated with reproducing light La from the side of a reproducing layer 4a of the disk and also a reproducing magnetic field Hr is impressed on the a region icluding the spot S of the reproducing light by the reproducing light La while rotatingly driving the disk, the reproducing layer 4a of a low temp. region B1 is initialized by the reproducing magnetic field Hr and the magnetization of the reproducing layer 4a of the low temp. region B1 is always directed to a fixed direction regardless of the magnetization direction of a recording state holding layer 4c and, as a result, the low temp. region B1 becomes a so-called front mask by masking the front side of the scanning direction of the spot S of the reproducing light. In a high temp. region B2, magnetism of an intermediate layer 4b disappeares and an exchange coupling in a recording layer is cut and the reproducing layer 4a is always magnetized in the direction of the reproducing magnetic field Hr.

Abstract: PROBLEM TO BE SOLVED: To adequately execute the high-speed access to a desired track while dealing with high-density recording. SOLUTION: The magneto-optical disk 10 is constituted by forming regions where concentric or spiral grooves 12 are interrupted in the mid-way parts of the recording tracks 11 formed with along the grooves 12 and forming pit patterns indicating the information on the recording tracks in these regions where the grooves 12 are interrupted.
