BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a system for making magnetic tape recordings and more specifically to a magnetic tape recorder system with independent recording and playback functions.
2. Description of the Related Art
In the most conventionally known application of a tape system for recording and playing back signals (whether analog or digital signals), the tape is drawn from a feeding reel and moved past a recording head, then past a playback head, to be finally wound up on a receiving reel.
The main fields of application of these techniques are:
a) the audio-visual field (magnetic tape recorders, video recorders) at professional, consumer, research, industrial, medical or other levels;
b) the data processing field with computers using tapes as data carriers.
In all the aforesaid applications, data can be recorded and played back either simultaneously or with delayed playback. An example of simultaneous recording and playback is conventional magnetic tape recorders and video recorders, where the recorded programs can be watched (or listened to) during the recording.
Delayed playback is where recording and playback occur at different times. In the case where only one conventional recorder is used, the operator has to wait for the end of recording before rewinding the tape and playing back the tape. The duration of the pre-recorded replay is necessarily longer than the duration of the original recorded sequence.
Under various circumstances, it may be advantageous to render the recording part of the device and the playback part of the device independently operable in time. This is the primary object of the present invention.
As used herein, "independently operable in time" means that the replay of the tape may begin not only after the recording is completed, but also while the recording is still in process. The present invention combines both of these possibilities, providing the operator with the option of replaying the tape after the recording is completed or replaying the tape, at a different speed than the recording tape speed, while the recording is in process.
SUMMARY OF THE INVENTION
In accordance with the present invention, there is provided a tape recorder system for physically separating the recording device from the playback device, and for inserting between the recording device and the playback device, a tape storing device. The two conventionally known devices (recording and playback) are adapted as necessary to interface with the storing device.
The tape recorder system according to the present invention includes a fixed element provided with a recording sub-assembly and a second element provided with a playback sub-assembly. The recording sub-assembly includes a feeding reel and a recording device. The playback sub-assembly includes a playback device and a receiving reel, the rotation of which is controlled by a motor. A circular intermediate reel is located between the recording sub-assembly and the playback sub-assembly. The intermediate reel is driven about its axis by a motor and includes a retractable bearing surface on its periphery for receiving the tape leaving the recording sub-assembly. A controlling roller, which directs the tape towards the playback sub-assembly, frictionally engages and is driven by the intermediate reel.
In the description of the invention provided hereinabove, the recording sub-assembly and the playback sub-assembly have been differentiated for clarity's sake. Those in the art will understand from reading the present description that the device according to the present invention is reversible, meaning that subject to a few minor adaptations relative to the direction and speed of rotation of the reels, the sub-assemblies are interchangeable. Also, each sub-assembly may include elements permitting recording as well as elements permitting playback.
