Abstract: PURPOSE:To eliminate necessity for rewinding before reproducing a recorded program by disposing (n) recording areas in the direction of the width of a tape, turning back at the time of T/n when defining a recording setting time to be T in the recording area and returning it to an initial position. CONSTITUTION:At the time of a reflecting recording mode, if a recording start time tB and a recording completing time tE are inputted to a system controller 8 from a terminal 12', the controller 8 obtains the recording setting time T according to T=(tE-tB)/n [(n) is the number of the direction of the width of the recording areas and even number]. Then, the controller 8 inserts a code indicating a turning back into a marker signal included in a sub-code supplied to the fixed contact (b) of a switch 19' at the time of the recording setting time T, switches a switch 10 to the contact (b) side and reverses the traverse of a tape. In such a way, at the time of the recording setting time during a recording, it is turned back and recorded, so that at the time of a reproduction it is not required to rewind but to simply treat it and improve operability.

Abstract: PURPOSE: To enable very low speed recording and high speed recording with a simple operation, by controlling variably a synchronizing signal applied to a pickup means and a reference signal applied to a servo circuit controlling the tape running speed, in a system unifying a video camera and a VTR.
CONSTITUTION: A signal formed with a vertical synchronizing pulse P
v from a frequency dividing circuit 54 and a horizontal synchronizing pulse P
h applied to a deflection circuit 63 is applied to a deflection coil 6. A luminance signal S
y is picked up from a pickup tube 61 and synchronizing pulses P
v and P
h are added at an addition circuit 17 to be an FM signal S
f at an FM modulation circuit 18 and it is applied to a magnetic head 24. A tape 3 running in a given speed to the head 24 is made change for the height toward one direction with the pulse from the circuit 54 and the running direction is inverted. The recording speed is changed by controlling the frequency dividing ratio of a frequency division circuit 53 with a signal from a control circuit 55.

Abstract: PURPOSE:To obtain a wide opening onto which an optical pickup device, etc., face and reduce the size of a disc cartridge by a method wherein the opening is provided so as to have an inclination from a direction in which the disc cartridge is inserted. CONSTITUTION:A cartridge main part 4 is a thin housing composed of a pair of an upper half 2 and a lower half which are made to butt against each other. An opening 11 onto which a disc turning driving means and an optical pickup device 13 which are built in a recording/reproducing apparatus face is provided in the main surface of the lower half. The opening 11 is formed from the center part of a recording disc 1 so as to have an inclination from a direction in which the cartridge is inserted. That is, the opening 11 has an inclination angle smaller than 45 degrees from a straight line which passes through the center of the recording disc 1 and is vertical to the direction in which a shutter is transferred.

Abstract: PURPOSE:To suppress the cost increase by compressing a digital video signal for plural channels, applying time division multiplexing to the signal and record ing the result on the same track. CONSTITUTION:Processing circuits 51-53 for three channels compress respectively 1st-3rd channel video signals and an audio signal. Video audio multiplexers/ demultiplexers 81-83 multiplex video data and audio data fed from the processing circuits 51-53 and output the result to a channel multiplexer/ demultiplexer 91. The channel multiplexer/demultiplexer 91 applies time division multiplexing to three channel data received from the multiplexers/demultiplexers 81-83 to synthesize them to one channel data. Thus, the digital video signal for plural channels is compressed and multiplexed in this way and the result is recorded on the same track.

Abstract: PURPOSE:To make the contact state on a magnetic tape and the process of wear of a preceding head and succeeding head of magnetic heads to be almost the same. CONSTITUTION:A recessed part 22 which is formed gradually shallower as it goes in the direction opposite to the rotation of a rotary drum 21, is provided on the rotary drum 21 in the connection with a window part 13. Then, the contact surface pressures of the preceding head 15A and succeeding head 15B are made almost the same without reducing an air film by increasing a succeeded space 18b, thereby the contact and wear states of both heads 15, 16 against the magnetic tape are made to be the same.

Abstract: PURPOSE:To simply adjust the height of a fixed head with high accuracy. CONSTITUTION:A track T1 where the control signal is recorded is formed on an adjustment tape together with the tracks T2 and T3 where the sine wave signals of frequency f2 and f3 are recorded. The center position of the T2 is coincident with the height of the upper end of a control heed Hc decided by a format, and the width of the T2 is coincident with an allowable error range. The height of the heed Hc is increased (position A) and a fact that the reproduced signals include the components of the frequency f2 and f3 is confirmed. At the same time, the level of the f2 is read. Then the height of the head Hc is reduced down to such a level where the component level, of the f2 is halved. Thus the height of the upper end of the head Hc is set equal to that decided by the format (position B). Thus the height of the heed Hc is adjusted based on the components of both f2 and f3 not on the level of the reproduction signal only. In such a way, the height of the head Hc can be simply adjusted with high accuracy.
