摘要:
A tape recorder or player with automatic azimuth control, utilizing a single pieozoelectric element inside the head's magnetic shield. A bimorph has one end rigidly connected to the head and the other end rigidly connected to the head support, for pivoting the head about an axis in line with the head gap.

A magnetic tape recorder or playback apparatus, especially suitable for tape having a large number of parallel longitudinal tracks, has a positioning device for independently correcting tracking and skew errors. A first positioning system uses two piezo-electric elements parallel to each other and equally spaced on opposite sides of the pivot axis, and a second positioning system arranged between the first two piezo-electric elements, having at least three piezo-electric elements regularly spaced around and extending longitudinally about the pivot axis.
摘要:
A method of and a device for automatically compensating the error in the angular position of a reproducing head, the upper half and the lower half of a track being scanned simultaneously, while the time difference between the zero passages of the signals is determined and a signal for the compensation of the angular error is derived therefrom.
