Abstract
An apparatus and method for scanning a moveable record medium, detecting the presence of signal information on the moveable record medium and halting the moveable record medium at the detected signal information or automatically rerecording the detected signal information. The method and apparatus is particularly adapted to function in a multichannel logging system, wherein the desired signal information is intermixed with low frequency time and information signals. The method and apparatus is capable of filtering out the low frequency signals while the tape moves at speeds between playing speed and up to 100 times playing speed, detecting if any signal information remains, and either halting the tape at the detected signal information or automatically rerecording it.
