Abstract
Abstract When the hold button is pushed the signals to the FM discriminators are switched from the signals on the tape to the signals from the record oscillators, which are tracking the signals on the tape (the recording heads are disconnected), and the output from the record oscillators provide constant hold signals. As the tape coasts to a stop the cycles of FM signal on the tape are counted by a counter. When the tape is rewound the total number of FM cycles the tape runs (including in the backward direction rewind coast) is counted. Then when the tape is placed in forward position again when the position on the tape passes the playback heads at which the hold was initiated the held signals are removed and normal operation continues from substantially the position at which the hold was initiated.

Claim 1
Independent Claim
307 words
The improvement in the control of a FM magnetic tape system having FM recording and playback apparatus including a recording oscillator and tape transport mechanism for moving the magnetic tape past the tape heads, the said system providing a programmed signal on playback operation from a prerecorded FM testing tape to a controller, the improvement comprising; a. means for operating the recording oscillator of the said tape system in accord with the said proGram material on the prerecorded tape during playback operation; b. means manually actuated for supplying a signal to the said transport mechanism for initiating a stopping of the tape; c. means cooperating with the said recording oscillator for providing a holding signal to the controller, the said held signal being a signal substantially equivalent to the signal on the tape at the initiation of the stopping of the tape; d. a preset counter for counting cycles of the FM signal on the magnetic tape and providing a control signal after a determined count; e. means cooperating with the said manually actuated stopping means and the said counter for counting the FM cycles on the tape that passes the playback head, after the initiation of the manually actuated stopping means, until the tape comes to a stop; f. means manually actuated cooperating with said said transport mechanism and the said counter for rewinding the tape a determined number of the prerecorded FM cycles on the tape; g. means cooperating with the said tape transport mechanism and the said counter for restarting the tape in the forward direction; and h. means cooperating with the said counter and the said signal holding means for switching the signal to the controller from the signal held by the holding means to the programmed signal on the tape at the position on the tape at which the stop was initiated.

The improvement in the control of a FM magnetic tape system having FM recording and playback apparatus including a recording oscillator and tape transport mechanism for moving the magnetic tape past the tape heads, the said system providing a programmed signal on playback operation from a prerecorded FM testing tape to a controller, the improvement comprising; a. means for operating the recording oscillator of the said tape system in accord with the said proGram material on the prerecorded tape during playback operation; b. means manually actuated for supplying a signal to the said transport mechanism for initiating a stopping of the tape; c. means cooperating with the said recording oscillator for providing a holding signal to the controller, the said held signal being a signal substantially equivalent to the signal on the tape at the initiation of the stopping of the tape; d. a preset counter for counting cycles of the FM signal on the magnetic tape and providing a control signal after a determined count; e. means cooperating with the said manually actuated stopping means and the said counter for counting the FM cycles on the tape that passes the playback head, after the initiation of the manually actuated stopping means, until the tape comes to a stop; f. means manually actuated cooperating with said said transport mechanism and the said counter for rewinding the tape a determined number of the prerecorded FM cycles on the tape; g. means cooperating with the said tape transport mechanism and the said counter for restarting the tape in the forward direction; and h. means cooperating with the said counter and the said signal holding means for switching the signal to the controller from the signal held by the holding means to the programmed signal on the tape at the position on the tape at which the stop was initiated.
Claim 3
Dependent Claim
21 words
The apparatus as claimed in claim 1 wherein the said means for providing a holding signal includes an integrating operational amplifier.
Claim 4
Dependent Claim
24 words
The apparatus as claimed in claim 1 wherein the means for restarting the tape in the forward direction includes a manually actuated restart switch.
Claim 5
Dependent Claim
36 words
The apparatus as claimed in claim 1 wherein the means for operating the recording oscillator in accord with the program material on the tape includes means for disconnecting the said recording oscillator from the recording head.
Claim 6
Dependent Claim
32 words
The apparatus as claimed in claim 1 wherein the said apparatus operates from one channel of a multichannel tape system to control and provide held signals for each of the prerecorded channels.
