  • Patent number: 4915522
    Abstract: The video tape log device includes a looseleaf binder with front and back covers connected to a page holder bearing a longitudinal spine and transverse page connectors in the form of openable rings or clips. The device also includes a plurality of pages, each being encased in plastic which can be marked and erased. The pages bear on both sides indicia in the form of marked columns for entering information identifying the particular tape involved and the segments of the tape by a condition code, by the segment title and by the position of the segment on the tape. The pages can also be colored or bear colored tabs to distinguish types of entries on the tape; for example, different types of movies. Moreover, the device can include a removable ink pen and an eraser, and, if desired, for a more permanent record, an indelible ink pen, and solvent to remove the ink, as well as a solvent applicator. Those items can be disposed in recessed pockets in one or both binder covers for ready access by the log user.
