摘要： A reproducing stylus traces a track of a recording medium, in which track an information signal is recorded as variations of geometrical shape, and reproduces as variations in capacitance the information signal thus recorded. The reproducing stylus comprises a reproducing stylus main structure having a tip portion with a sliding contact face for slidingly contacting at least one track of the recording medium, and an electrode disposed on the reproducing stylus main structure to trace one track and reproduce the information signal as the variations in capacitance in accordance with the variations in geometrical shape. The electrode has an end edge and side edges. The side edges are substantially parallel at least in the vicinity of the tip portion of the reproducing stylus main structure. The sliding contact face has a leading part and a trailing part respectively at the foremost end and the rearmost end in a relative sliding direction of the sliding contact face on the recording medium. The end edge of the electrode is at said trailing part, the length l of the sliding contact face in the relative sliding direction being larger than the width d of the end edge of the electrode in a direction perpendicular to the relative sliding direction.

摘要： An information signal recording system records an information signal, a first and a second reference signals for tracking control, and a third reference signal for switching the first and second reference signals at the time of reproduction on a recording disc. The first and second reference signals are alternately recorded at positions intermediate between centerlines of adjacent information signal tracks. The third reference signal is recorded at a predetermined position on every information signal track. A reproducing system reproduces the information signal together with the third reference, and the first and second reference signals by a single reproducing element. A tracking control signal is produced from the first and second reference signals switched by the third reference signal separated from the reproduced information signal.

摘要： An information signal recording system records an information signal, a first and a second reference signals for tracking control, and a third reference signal for switching the first and second reference signals at the time of reproduction on a recording disc. The first and second reference signals of different frequencies are alternately recorded on intermediate parts of the recording disc, at positions between centerlines of adjacent information signal tracks. The third reference signal of a still different frequency is recorded at a predetermined position on every information signal track. A reproducing system reproduces the information signal together with the third reference, and the first and second reference signals by a single reproducing element. A tracking control signal is produced from the first and second reference signals switched by the third reference signal separated from the reproduced information signal.

摘要： An information signal recording system separates a color video signal into a luminance signal and a carrier chrominance signal. The frequency of the separated carrier chrominance signal is converted to a lower frequency band. A carrier is frequency modulated with at least one audio signal which is mixed with the separated luminance signal and the frequency converted carrier chrominance signal. A carrier is frequency modulated with the mixed signals, and recorded as a main information signal on a main information signal track of a recording medium. A system for reproducing the recording medium reproduces the recorded main information signal from the recording medium. The reproduced main information signal is frequency demodulated, and the resulting output signal is separated into the luminance signal and the frequency converted carrier chrominance signal. The converted carrier chrominance signal is returned to the original frequency and mixed with the separated luminance signal to produce a reproduced color video signal. The frequency modulated audio signal is separated from the frequency demodulated main information signal. The separated frequency modulated audio signal is then demodulated.

摘要： The present invention relates to a magnetic recording/reproducing apparatus capable of performing a fast forward reproduction, a fast backward reproduction, a still picture reproduction and the time-lapse recording. The magnetic recording/reproducing apparatus according to the present invention realizes a preferred reproduced image containing no noise-bar, by correcting deviation of magnetic heads mounted on an upper drum from intended tracks depending on a difference in tape running speed between a recording operation and a reproducing operation by tilting the upper drum about a predetermined pivot point with respect to a lower drum having a lead formed thereon. Further, the magnetic recording/reproducing apparatus according to the present invention realizes a preferred reproduced image containing no noise-bar even for a signal recorded in a narrow track pattern in an extended time recording mode, by correcting a slight separation of the magnetic tape from the lead due to a tilt of the upper drum, by tilting the lower drum.
