The head used fixed scanning but moved down the tape to the next track once the end of the quickly moving tape (240 ips with 300 tracks to a ½” tape) had been reached.

One of the advantages touted for the system was the low production cost of both the tapes and the hardware but consumers never had the chance to try it. Problems with the poor picture quality caused by a very brief interruption to the picture as the head moved down led to delays in production. In

From then it became clear that 'rotating-head' helical scan recorders were the way forward with superior sound and picture quality. However the expense of rotating-head machines ($ 2000 for a machine in 1956) meant that work continued on developing a consumer stationary-head machine for some time
