The role of the recorder and the basic composition structure

The video recorder is to record TV images and sounds, which can store TV program video signals, and you can re-send them to a television transmitter or transfer them directly to tape recorders in the TV. The video recorder is a recording and playback device in a closed-circuit television monitoring system, which requires a recorder that can be recorded very long, and most of the monitoring systems can record 24h ~ 960h recording. In addition, the recorder must also have a remote control, which can easily operate a remote operation of the recorder, or automatically operate the recorder with a control signal in a closed teleconcut system. The basic composition of the recorder includes: head system, tape drive system, video signal processing system, servo system, mechanical control system, audio signal processing system, power supply, etc. 1 Head System: The head system includes a video recording magnetic head, an audio record magnetic head, a control signal recording a magnetic head, an imaginating head, and the like. The video magnetic head is a key component of the tape recorder, and the video signal and the magnetic signal of the magnetic signal are converted. 2 Tape drive system: The recorder drives the magnetic bandway belt by the main guide by means of the pressure of the pressure pulley. After the tape is placed in the recorder, the mechanical device automatically exports the tape to complete the belt task, which is done by the tape drive system. 3 Video Signal Processing System: This system is primarily reproduced to the recording of video signals and audio signals. Therefore, the system consists of two parts of the recording channel and the playback channel. 4 servo system: The servo system includes a drum servo, a primary axis servo, and a tape tension servo. Its basic function is to ensure the smooth progress of the recorder signal record and the playback process. It is a sample, feedback, feedback, feedback, and a reference signal to control the control amount object by comparing the reference signal by mechanical or electronic circuitry. System error is limited to a given range. 5 Mechanical control system: Mainly composed of wearing retreat mechanism, with cassette automatic loading and unloading mechanism, tape operation mechanism, and motor drive and various positioning rods, guiding rods. The mechanical control system is composed of functional operation buttons, logic circuits, and electromechanical action components.
