Latest Patents

Yabu's latest patents include a speed control system for a multiple speed tape recording and reproducing apparatus. This system utilizes a transducer head to reproduce a tape speed indicative signal recorded along the edge of a recording tape. The frequency of this signal is compared with several reference values to determine its corresponding frequency band. If the reproduced speed signal does not match the predetermined frequency, a motor drive signal is generated to adjust the tape speed accordingly.

Another significant patent involves a magnetic tape recording and reproducing apparatus that features a means for recording a cue-signal. This cue-signal marks a predetermined point on the magnetic tape where video signals are recorded. The cue-signal is recorded using a full erasing head, which receives a cue-signal current at a frequency lower than that of the erasing current. This innovative approach synchronizes the rotation of the rotary head with the tape movement, enhancing the functionality of the recording apparatus.
