How is the electrical signal taken out of the vcr rotating head? Is is inductive, capacitive, inductive, slip rings etc? Also, how is the audio taken off the tape? I can understand the audio coming off of a separate linear track. But someone told me that some machines put the audio down on the helical track. This would appear to me to be extremely difficult to achieve. It would be hard to get scan to scan closure without some audible artifact. Dave Crook dc@hpmtlx.hp.com
