Video Recorder(VCR)
The Video Recorder is made up of several components. The main components are the magentic tape and the head drum. Video signals are recorded on magnetic tape. These signals conrol the recorder and the image synchronization. In order to record video signals, the tape has frequencies ranges of 0 hertz to 4 million hertz. In order to play back these video signals, the information is stored on a polyster layer coated with a magnetic material. The video audio heads in the video recorder produce a fairly weak magnetic field which is applied to the magnetic material on the tape. Normally, the tapes consist of four layers. The carrier is a wafer-thin polyster layer which is coated on the back with an anti-static material. The magnetic material is applied to the polyster carrier on the front of the tape. To prevent this metal from wearing down, a topcoat is added to the tape.
