Granted: 1992-06-16
Abstract: ABSTRACT OF THE DISCLOSURE           A recording and/or reproducing apparatus employs azimuth-pair-head in a rotary head drum.  The rotary head drum is axially shifted by a head shifting means. First tracks are formed on a magnetic tape during forward driving of the magnetic tape across the rotary head drum.  On the other hand. second tracks are formed adjacent to the first tracks during reverse driving across the rotary head drum. Since the first and second tracks are formed by means of the azimuth-pair-head, azimuth gaps thereof will have different or symmetrical obliquity to each other.  This successfully avoids cross-talk between adjacent tracks to allow formation of the first and second tracks in a tightly arranged fashion.  As a consequence. high-density longitudinal recording without cross-talk between adjacent tracks becomes possible.

Abstract: Abstract of Disclosure A strain wave  gearing comprising a circular  spline, flexspline  disposed  inside  the  circular  spline,  a  wave generator for deforming the flexspline into,  for example, an ellipsoid  and  a  motor  for  rotating  the  wave  generator  to produce  a  relative  rotation  between the  flexspline and  the circular spline.  The strain wave gearing is sometimes termed a harmonic drive transmission.   In the strain wave gearing, the tooth face of each of the splines is formed in line with a mapping curve which  is a similarity transformation having a reduction ratio of  1/2  applied  to a movement locus  of  the flexspline  to  the  circular  spline  in  accordance  with  the configuration of the wave generator, the transformation being effected  on  a  reference  point  where  the  splines  are transferred from the contact condition to a disengagement from each other.   Thus,  the teeth of the  flexspline engage with those  of  the  circular  spline  in  the  broad  extent  of  the engagement region.
