It is possible to improve the frequency response and bandwidth of an audio recorder by increasing the tape speed. So early attempts at video recording adopted the obvious approach. They ran the tape very fast to widen the bandwidth sufficiently to cope with video. Engineers did succeed in recording television signals this way. But when a reel tape runs very fast, it runs out very quickly. So even a large reel only lasts for a few minutes. Also, machines of this type are mechanically very unstable. It is very difficult to get the synchronisation pulses accurately timed. This is why this technique called Longitudinal Video Recording (LVR) fell by the wayside. Recording speeds for different formats are given in Table 33.1.
