  • Patent number: 5420729
    Abstract: Automatic head cleaning apparatus and method for checking insensitivity of a VCR video head and for performing a head cleaning operation for a predetermined period. When the insensitivity of the video head is not corrected even after the head cleaning operation for the predetermined period, the VCR tape is ejected. Simultaneously, an alarm notifying a failure of the VCR is activated. A VCR head cleaner is also provided that is in close contact with a VCR drum head due to a magnetic reluctance force during the head cleaning operation. The VCR head cleaner prevents the video head from being subjected to adverse impact and frictional force, and is easily installed requiring no additional space within the VCR. Furthermore, the cleaning operation is automatically completed.
