Latest Patents

Ikushima's latest patents include a recording head arrangement for video signal recording and/or reproducing. This innovative arrangement is designed for use in devices where a video tape is helically wound on a drum carrying recording heads. The system allows for the division of video signals to represent upper and lower half images on a screen. The recording head arrangement features first and second heads mounted adjacent to each other, both having the same azimuth angle inclined in a specific direction. Additionally, third and fourth heads are positioned 180 degrees from the first and second heads, with their azimuth angle inclined in the opposite direction. This configuration enables the scanning of heads to form tracks for recording and reproducing video images effectively.

Another significant patent by Ikushima is a video recording and reproducing system that operates in two selectable modes. In the 'standard mode,' only one field of television video signal is recorded on each oblique track. Conversely, in the 'period expansion mode,' multiple fields of the television video signal can be recorded on each track. This innovative system allows for a switchover between modes by adjusting the relative speed between the recording medium and the rotary transducing head assembly.
