Abstract: In a recording/reproduction apparatus, when a rotational-speed-mode setting instruction is received from an I/F unit, a CPU reads out a control procedure from a storage device, controlling other components in accordance with the procedure. As a result, a node switch driving circuit controls field windings of a pulse motor to a switching sequence, driving the pulse motor to rotation at a predetermined rotational speed. Since the control is feedback control, the pulse motor rotates at the predetermined rotational speed specified by an instruction setting a rotational-speed mode with a high degree of reliability. Data can thus be recorded into and reproduced from a magnetic disk at a variable speed.
Abstract translation: 在记录/再现装置中，当从I / F单元接收到转速模式设置指令时，CPU从存储装置读出控制过程，根据该过程控制其他部件。 结果，节点开关驱动电路将脉冲电动机的励磁绕组控制到开关序列，驱动脉冲电动机以预定转速旋转。 由于控制是反馈控制，所以脉冲电机以以高可靠性设定转速模式的指令指定的预定旋转速度旋转。 因此，可以以可变速度将数据记录到磁盘中并从其再现。

Abstract: A signal processing operation includes periodic recordation of information, such as television image and audio signals, on a recording medium (11). The information is recorded for a predetermined period of time provided that a signal level of the recorded image and audio signals exceeds a predetermined threshold. After the recording operation is completed, a recording standby state follows during which no recording is performed on the recording medium. The information contents are sufficiently understandable by carrying out the periodic recording operation while the hard disk (11) can be efficiently utilized to provide additional recording space thereon.

Abstract: A disc cartridge having a disc-shaped recording medium, such as an optical disc or a magneto-optical disc, rotatably housed within a main cartridge body. The disc cartridge has a main cartridge body made up of an upper cartridge half and a lower cartridge half, and a disc-shaped recording medium rotatably accommodated within the main cartridge body. A recording and/or reproducing aperture is formed in at least one of major surfaces of the main cartridge body. A shutter is mounted for movement along a sidewall section of the main cartridge body between a position closing the aperture and a position opening the aperture. There is provided an inclined portion in the aperture inclined with respect to the inserting direction of the disc cartridge.

Abstract: Video and information signals, such as audio signals, are recorded (16, 17) in oblique tracks on a magnetic tape (18) having a wrap angle of no more than 180 DEG by timebase converting (3A, 3B, 6a, 6b, 11) at least the video signal which then is time division multiplexed (14A, 14B) with the information signal. The time division multiplexed signals are recorded (16, 17) sequentially in a length of rack that is less than the wrap angle to form successive tracks.

Abstract: A video signal recording apparatus having luminance and chrominance signals multiplexed on a time division basis. In signal recording, a two-channel head arrangement (10A, 11, 17A; 10B, 11,17B) with a gap between different azimuths performs two scans on one field of recording signals for two tracks concurrently. Because the same kind of chrominance signal is subject to each of the different azimuths, not only normal speed reproduction but also variable speed reproduction is performed with high picture quality.

Abstract: A magnetic erasing head (5) of a double effective gap type which has gaps (g1,g2) different in width to each other, a magnetic center core (7) positioned between the gaps and a winding (6) for inducing a magnetic flux. An erasing signal is supplied to the winding (6), the wavelength of the erasing signal having a predetermined relationship relative to a length of the magnetic center core so that the residual magnetism induced in the tape coating by the fluxes generated across the gaps (g1,g2) forms closed flux paths extending depthwise into the coating.

Abstract: An FM multiplex audio system wherein either stereo signals or signals of two languages can be simultaneously transmitted and where switch means are provided so as to selectively delay either of the language signals so that the listener will hear a first language and then after a delay a second language. Means are also provided for muting either of the language signals if desired.

Abstract: Disclosed are an audio signal recording apparatus and method for recording in a plurality of tracks (T) a video signal and an audio signal of say four channels corresponding to the video signal, the tracks constituting one segment. The audio signal is recorded in a recording area (PA) separate from that (VA) for the video signal on a tape (4). The audio signal of the four channels is divided into groups each associated with a plurality of channels. Each group of audio data is recorded in one of audio signal recording blocks (PA12, PA34) obtained by dividing the audio signal recording area (PA) in the longitudinal direction of the tracks (T). The groups of audio data are each given a priority depending on the importance of the data, and data of high priorities are recorded in blocks (PA12) that are farther away from the track ends where the contact between tape (4) and head (1, 2) may be unstable.
