摘要： A rotary magnetic recording and reproducing apparatus includes a stationary cylinder formed on a lower portion of an outer peripheral surface thereof with a guide lead for guiding a lower edge of a magnetic tape and defining a tape running face on an upper portion of the outer peripheral surface thereof, a first bulge portion formed on an upper edge portion of the tape running face of the stationary cylinder on a tape leaving side of the upper edge portion of the tape running face and a second bulge portion which is smaller in height than the first bulge portion and formed on the upper edge portion of the tape running face on the tape leaving side thereof and in the vicinity of the first bulge portion on a tape incoming side of the first bulge portion. The first bulge portion serves to relax shock or vibration of a magnetic tape leaving the magnetic head and the second bulge portion serves to improve "head-touch" of the magnetic tape.

摘要： A rotary cylinder device for helical scan type magnetic recording/reproducing apparatus including a rotary cylinder having an axis of rotation arranged in opposition a stationary cylinder in the direction of the axis of rotation with a small gap therebetween. The rotary cylinder has an end surface facing the stationary cylinder and an outer peripheral surface, recesses formed in the end surface and opening in the outer peripheral surface so as to extend therefrom radially inwardly over a small distance. Each of the recesses has a leading end wall and a trailing end wall, as viewed in the direction of rotation of the rotary cylinder. Magnetic heads are fixed to the rotary cylinder and are positioned in the recesses and have outer extremities projecting beyond the outer peripheral surface of the rotary cylinder. The distance between the leading end wall and the trailing end wall of each recess progressively decreases towards the axis of rotation of the rotary cylinder so that the distance is greatest at the outer end of the recess adjacent the magnetic head and the smallest at the inner end of the recess remote from the magnetic head.

摘要： A flying erase head for flying erasing which is used for improving the picture quality is provided on a rotating drum so as to be spaced substantially 180 degrees from the video head having first and second video head chips integrally fixed on a video head base. Therefore, a high picture-quality helical scan type magnetic recording and/or reproducing apparatus can be provided which is able to prevent the picture quality from being deteriorated by the vibration of the video head due to the rotation, and to satisfactorily make the over-writing on the tape and the assemble mode operation upon recording.

摘要： A rotary magnetic head cylinder device for use in a helical-scanning system video tape recorder has a projection provided on a tape running race of a stationary lower cylinder near a location at which a magnetic tape leaves from the lower cylinder. The projection is preferably integral with the tape running race and has a small area which is defined by a shoulder circumferentially extending identically with a tape guide shoulder contouring the lower edge of the tape running race and which spreads perpendicularly to the tape running race, and an upper surface coplanar with the top face of the lower cylinder, and a height defined by a protruded length radially outwardly toward the outer circumferential surface of the lower cylinder. The projection serves to reduce vibrations of the magnetic tape generated when the video head carried by the rotary upper cylinder leaves from the magnetic tape.
