Because, I mean, those things are line accurate by necessity, so that once you have them time coded, you ought to be able to get sample accurate registration of the converted audio, when driven from house time. In many ways things like DAT and DASH might be trickier than that. <The lurker decloaks> The helical scan recorder to which you likely refer was the Sony PCM-F1. It was a two part device that had an audio processor (aka PCM adapter) connected to a portal Betamax transport. http://www.thevintageknob.org/sony-PCM-F1.html http://mixonline.com/TECnology-Hall-of-Fame/1981-sony-pcmf1/ I don't believe that most Betmax systems had the ability to lock to standard SMPTE time code. That didn't usually happen until one was faced with 3/4" Umatic VTRs. Even then it was only on the broadcast models (BVU series) not the lesser "industrial" machines of the VO Series. I think that the PCM-F1 was basically an adapter that presented something that the recorder could handle as a nominal video signal. As such it may have been used with various recorders, but it's most often associated with the SL-2000 model. That pair were cosmetically mated and made a nice portable (relatively) package. At around that time I was a teenage volunteer at a local cable channel that had Sony industrial Betamax infrastructure. We lusted after the PCM-F1.
