摘要： PURPOSE:To improve the output level of a color signal and the picture quality by setting the recording current of an ME tape (metal vapor-deposited tape) to a value slightly lower than ORCE. CONSTITUTION:A recording amplifier 3 is set to the ME tape mode, and thereby, the video signal processed by a video signal processing circuit 2 is amplified by the recording amplifier 3 so that the recording current value is 26+ or -5mApp, and this amplified signal is outputted to magnetic heads 5 and 5 and is recorded on the ME tape. This recording current 26+ or -5mApp is slightly lower than ORCE (32+ or -5mApp). Since the recording current of the ME tape is set to a value slightly lower than the recording current value for which the reduction rate of the output level of a luminance signal to the input level of the video signal is minimum, namely, ORCE in this manner, the output level of the color signal and the picture quality are improved.

摘要： PURPOSE:To eliminate necessity for switching a recording current for each mode and tape by forming the crossover of the optimum recording current for first and second metal tapes at the midpoint of a carrier center for the normal mode and high band mode. CONSTITUTION:By a method such as changing the thickness of a magnetic layer in the tape, the crossover is formed in 6MHz to be the midpoint between 5MHz, which is the carrier center of the normal mode, and 7MHz which is the carrier center of the high band mode in the frequency character of MP and ME tape. When the optimum recording current in this 6MHz is made flow from a recording amplifier 8 to a head 9 as the set recording current, the recording current can be one type of the unified current even in either the normal mode or high band mode and even for either the MP tape or ME tape. Accordingly, circuit configuration can be simplified.

摘要： PURPOSE:To reduce an error rate of a reproduced PCM audio signal by controlling a recording current fed to a rotary head to be an optimum value according to a type of a cassette tape and a recording format of the PCM audio signal in the case of recording the PCM audio signal. CONSTITUTION:A sensor 4 in the case of recording a PCM audio signal detects a type of a tape cassette as to whether the tape is a standard type coating (MP) tape, a metal vapor deposition (HGMP) tape or a vapor deposition (ME) tape based on an ID hole of the tape cassette and gives its sensing output to a system controller 3. Moreover, the user uses keys 5 to designate various modes of the VTR such as PCM audio recording mode as to whether the mode is an NRTML mode, an L mode or an N mode. Thus, the recording current fed to rotary heads 1A, 1B is controlled to be an optimum value automatically. Thus, an error rate of a reproduced PCM audio signal is minimized at reproduction.

摘要： PROBLEM TO BE SOLVED: To provide a device and a method enabling automatic adjustment of the output level of a video signal.
SOLUTION: Setting for a level adjustment for adjusting the output level of the video signal outputted from a video signal output terminal is performed in the device. The signal adjusted in the level adjustment is fed back and inputted, level detection based on the feed back signal is performed, and an optimal parameter set point in the level adjustment is determined and stored in a memory. By adopting this configuration, manufacturing cost is reduced since level adjustment by the use of an oscilloscope becomes unnecessary. Moreover, by adopting a configuration for performing level adjustment each time when power is turned on or at fixed time intervals, optimal level adjustment in accordance with the characteristics of elements becomes possible, even when the characteristics of each device and element change owing to changes in temperature, humidity, etc., caused by changes in season, or their secular changes.

摘要： PROBLEM TO BE SOLVED: To realize a synchronizing separator circuit in which production of jitter is suppressed, its capacitor is built in an IC by decreasing the capacitance of the capacitor, the number of IC terminals is reduced, the circuit configuration is simplified and the power consumption is reduced. SOLUTION: A detector DET1 operated for an active period of a clamp pulse CLMP and a clamp pulse detector DET2 operated for an inactive period of the clamp pulse CLMP are provided to the synchronizing separator circuit. When no synchronizing signal is inputted, the detector DET2 clamps the output level of the clamp circuit to be a clamp DC voltage VDC. When the synchronizing signal is inputted, the detector DET1 is used to set a level at an output terminal TS to the clamp DC voltage VDC. Then a leakage adjustment section 10 suppresses the occurrence of a horizontal sag, then the generation of jitter is suppressed and the capacitance of a capacitor C1 is reduced and the capacitor is built in an IC and the number of terminals of the IC is decreased.
