Abstract

A tape recorder system having separate and independently controllable recording and playback devices with a variablecapacity tape storage between the recording and playback heads and means to position recorded tape accurately at the playback head so as to enable the recorded portion of the tape to be instantly played back upon demand. The system is also capable of re-recording previously recorded material with new material being recorded therewith, and the system is also capable of playing back action in slow motion as the action is occurring.

Claims

1. A tape recording device comprising:

a. a recording head;

b. a playback head separated therefrom;

c. a recording tape mounted for movement past said recording and playback heads;

d. first drive means for moving said tape past said recording head when said first drive means is energized;

e. second drive means for moving said tape past said playback head when said second drive means is energized;

f. first switch-operated means for simultaneously energizing said first and second drive means and for substantially deenergizing said second drive means when the portion of said tape initially at said recording head when said first drive means was energized has been moved to and positioned at said playback head;

g. a variable-capacity tape storage means in the path of said tape between said recording and playback heads for the reception and storage of said tape that is driven past the recording head by said first drive means when said second drive means is de-energized.

2. A tape recording device as set forth in claim 1 and further including:

h. second switch-operated means for energizing said second drive means at a desired time subsequent to the actuation of said first switch-operated means.

3. A tape recording device as set forth in claim 2 wherein said second switch-operated means also de-energizes said first drive means.

4. A tape recording device as set forth in claim 2 wherein said second switch-operated means continues the energization of said first drive means.

5. A tape recording device as set forth in claim 4, and further including:

i. means to vary the speed of said second drive means relative to the speed of said first drive means.

6. A tape recording device as set forth in claim 4 and further including:

i. means operable in response to operation of said second switch-operated means for reading the signal on said tape at said playback head and for simultaneously recording such signal on said tape at said recording head.

7. A tape recording device as set forth in claim 6 and further including:

j. means operable in response to operation of said second switch-operated means for recording an external signal on said tape at said recording head.

8. A tape recording device comprising:

a. a recording head;

b. a playback head separated therefrom;

c. a recording tape mounted for movement past said recording and playback heads;

d. first drive means selectively energizable to move said tape past said recording head;

e. second drive means selectively energizable to move said tape past said playback head;

f. a variable-capacity tape storage means in the path of said tape between said recording and playback heads for the reception and storage of tape when said first drive means is energized and said second drive means is de-energized;

g. means to energize both of said drive means to move said tape simultaneously past both of said recording and playback heads;

h. means responsive to a predetermined amount of movement of said tape past said recording head for de-energizing said second drive means and for holding said tape against movement past said playback head.
