A combined camera and ¼-in. VTR unit was modified to allow its 10 min of recording time to be increased to 21 min. This was accomplished by using thinner tape and a smaller hub in the ¼-in. cassette while increasing the amount of tape by about 50%, and increasing the recording density by about 40%. A signal-to-noise ratio of over 47 dB was achieved, with a bandwidth of 3.6 MHz (−3dB), by the development of a metal head and improved metal particle tape. Design criteria for maintaining tape motion stability are described.
