>Old-Time PIClisters -- > I need your help in developing a new device -- a piezoelectric servo. Why not talk to some oldtime broadcast television engineers? Ampex did this many years ago - they used piezo positioners to change the head position at least one of their old videotape recorders. I don't exactly recall the purpose - I think it was to slew the head's azimuth on alternate scan lines. It was a noisy, fairly high power device - thats about all I remember about it. dwayne Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (403) 489-3199 voice (403) 487-6397 fax
