ABSTRACT:
A video tape index conveniently catalogs programs on a video tape cassette. The index comprises an indexing card laminate having a core ply printed with grids and headings suitable for organizing information pertinent to video tape programs. Clear films are bonded to the core ply. The outer surfaces of the clear films have matte finishes suitable for accepting a writing instrument. If the information is written in pencil, the entered information can be easily erased and replaced when the cassette programs are changed. The indexing card further comprises a calender for listing information pertinent to further programs to be recorded. The indexing card also contains a calibration chart for correlating equipment counter readouts with elapsed time.
