摘要:
A recording/reproducing apparatus with an editing function delivers a control command to a tape running servo through a system controller of a system control system at the time of phase adjustment, thus to control a capstan motor. At this time, servo status information is delivered from the capstan motor to the system controller through the tape running servo. Whether or not adjustment of tracking is completed is judged in accordance with the above information to automatically carry out adjustment of tracking, thereby making it possible to automatically conduct, at the time of editing, adjustment of tracking, which was carried out by manual operation prior to editing work, without supplementing a new circuit.

In an apparatus for recording video signals within recording tracks extending obliquely across a magnetic tape, having a rotary drum with first and second pairs of heads spaced from each other pair by a distance corresponding to one track pitch in a direction parallel to the axis of the rotary drum for recording video signals simultaneously on two recording tracks, while sequentially recording video signals on the magnetic tape within the recording tracks the video signals are recorded on said magnetic tape for longer than at the time of normal recording in such a manner that one of the two recording tracks on which the video signals are recorded by one of the second pair of heads overlaps part of the other recording track which is next to the one recording track and on which the video signals are recorded by one of said first pair of heads, so that by controlling the moving speed of the moving means in such a way so as to be slower than the normal moving speed at the time of normal recording, reductions in the signal to noise ratio can be avoided, and effective long time period recording can be achieved.

A tracking control circuit for use in a composite digital video tape recorder, wherein the phase of a control signal is adjusted on the basis of a reproduced envelope signal in an interval of low correlativity to recorded contents out of the composite digital video signal reproduced by a recording head, so that the tracking position of the recording head relative to a video track is controlled to a predetermined proper position. In this circuit, accurate tracking control can be achieved at enhanced precision without enlarging the circuit scale or increasing the production cost.

摘要:
An optical deflection apparatus includes a signal light source configured to emit signal light having one or more wavelengths, a control light source configured to emit control light having a wavelength different from the wavelength of the signal light, a thermal lens forming optical element including a light absorption layer configured to transmit the signal light and selectively absorb the control light, and a beam-condensing unit configured to cause beam-condensation of the control light and the signal light at different convergence points in the light absorption layer. The thermal lens forming optical element causes convergence and divergence of the control light and the signal light on an incidence plane of the light absorption layer or its vicinity in a light traveling direction, wherein a thermal lens is reversibly formed in the light absorption layer due to a temperature increase occurring in a region where the control light is absorbed and its peripheral region, and the thermal lens changes a refractive index to change a traveling direction of the signal light.
