Abstract
Apparatus for displaying the relative locations of particular information recorded on a movable record medium, such as a magnetic tape, the particular information being represented by a predetermined signal. Electronic pulses are generated corresponding to the movement of predetermined amounts of the record medium past a reference position. A bidirectional counter counts these pulses so as to derive a count representing the amount of medium which has been moved past the reference position, and also representative of the relative position of that record medium which then is juxtaposed the reference position. An indicating signal is produced in response to the predetermined signal; and a memory, having a plurality of storage locations corresponding to the counts of the counter, stores an indicating signal at a storage location which corresponds to the present count of the counter at the time that the indicating signal is produced. A display is responsive to the signals stored in the memory for displaying the locations on the record medium at which the predetermined signals are recorded. In one embodiment, the display not only provides indications of the locations of recorded predetermined signals, but also provides a cursor corresponding to the approximate present position on the record medium whereat information then is being recorded or played back by the user of the apparatus.
