摘要： A driving element which performs driving according to a level of a voltage signal to be transmitted optically, a modulation current driving circuit configured to supply a modulation current modulated by the driving element to a light source for optical communication configured to convert a current signal into light and to output the light, and a constant current supply circuit configured to supply a constant current to the light source for optical communication are included. Then, when the voltage signal is at a first level, the driving element is turned on and the modulation current driving circuit supplies the modulation current to the light source for optical communication. When the voltage signal is at a second level, the driving element is turned off and the modulation current driving circuit stops supplying the modulation current. The present technique can be applied, for example, to an optical transmission system.

摘要： In a case where a main stream and a control signal are transmitted in parallel between two devices, transmission of the main stream is continued without interruption of the transmission of the main stream even in a case where communication quality of the control signal is deteriorated. Provided is a transmission control device including an information acquisition unit configured to acquire a channel change request transmitted from a reception device in a case where communication quality of a control signal transmitted through a first channel and received by the reception device being poorer than first quality has been detected, and a transmission control unit configured to start transmission of the control signal to the reception device through a second channel different from the first channel in a case where the channel change request has been acquired, in which the transmission control unit stops transmission of the control signal through the first channel in a case where a predetermined condition has been satisfied since the start of transmission of the control signal through the second channel.

摘要： A cable may be satisfactorily used that has a specific function such as a register that holds specification data and a current consumption unit such as an element for adjusting signal quality. The cable is connected between a first electronic device and a second electronic device. A determination unit determines whether or not the first electronic device is a compatible electronic device. A control unit performs control to operate in a compatible mode when the first electronic device is a compatible electronic device and operate in a non-compatible mode when the first electronic device is not a compatible electronic device on the basis of the determination result by the determination unit. Furthermore, an electronic device is connected to an external device via the cable. The determination unit determines whether or not the cable is a compatible cable. The control unit performs control to operate in the compatible mode when the cable is a compatible cable and operate in the non-compatible mode when the cable is not a compatible cable on the basis of the determination result by the determination unit.

摘要： There is provided a magnetic recording medium including a magnetic layer. The magnetic layer has a servo signal recorded thereon by magnetizing a part of the magnetic layer in a first direction. The first direction contains a component of a perpendicular direction that is perpendicular to a top surface of the magnetic layer. The magnetic layer is pre-magnetized in a second direction before recording of the servo signal. The second direction contains the component of the perpendicular direction. The second direction is opposite to the first direction.
