摘要： PURPOSE: To surely record a TV signal on each track with less omission by forcedly performing the intermittent advance of a head to an adjacent track at a high speed by supplying an electric current to the driving coil of a recording element.
CONSTITUTION: When a shutter button 12 is depressed after frame-wise recording is set at an operating section 23, a motor 11 is rotated by means of a signal from a head shifting motor controlling circuit 36 and a head 26 is moved in the advance direction. On the other hand, an electric current is supplied to a driving coil by means of a signal from an actuator control circuit 35 and the head 26 is displaced for a fixed time in the direction opposite to the advance direction. When such arrangement is made, the recording locus of the head 26 against a recording medium 18 becomes a closed circle during the period of one frame recording. Therefore, the recording element can be moved in a short time when it is advanced to an adjacent track.

摘要： PURPOSE:To stabilize the revolution of a rigid drum by forming a dynamic pressure air bearing within a microgap between the cylinder part of the rigid drum and a revolution driver part in a high-speed revolution mode. CONSTITUTION:When a motor shaft 37 is revolved after a motor 36 is driven, a magnetic drum 13 is revolved clockwise at a high speed. At the same time, the rotary phase of the drum 13 is detected by a rotary pulse pickup head 41. Thus the air within a circular gap between the drum 13 and an inside cartridge holder 35 flows toward an arrow mark. Therefore a dynamic pressure air bearing 42 is formed between the inside of the drum 13 and the holder 35 over the entire length of the lengthwise direction and over the entire circumference of the drum 13. The drum 13 changes its position in the direction where the core deflection of the drum 13 is compensated centering the connected part with the shaft 37. Finally the drum 13 is revolved with

CONSTITUTION:An NTSC type composite video signal inputted to a terminal 38 is delayed 39 by 1/2H (H: horizontal scanning period) and then supplied to a clamping circuit 40. The input video signal, on the other hand, is supplied to a delay circuit 41 as well, where the signal is delayed by as light extent enough to correct the excessive error of the delay extent of the circuit 39 and then supplied to a clamping circuit 42.

摘要： PURPOSE:To always bring stably a magnetic head into contact with a rotary type magnetic recording medium by moving a head carriage capable of rotary motion, consisting of two members and a spring, on the specified surface of a cam along a main guide bar by a feed screw. CONSTITUTION:The first member A is inserted in a main guide bar 5, and the second member B is set so that they may be separated each other through spring members 12, 13. The contact part 18 of member A contacts a guide member 6 having the surface of cam, and the engaging part 23 of member B engages with a transport screw 7. Under such constitution, the screw 7 is turned by a motor 11, and the carriage moves in a stabilized condition. Thus, as the members A, B are in the engaged condition possible to turn, by spring members 12, 13, effect of the deflection of screw 7, if any, is absorbed between the members A, B. The magnetic head 17 can always move stably in contact with the rotary type magnetic recording medium D.

摘要： PURPOSE:To perform long-time recording and reproduction and to obtain a reproduced picture with high definition even when a small-sized rotary recording medium is used, by alternating the periods of rotation of the rotary recording medium, i.e. an integral multiple of the horizontal scanning period of a TV video signal for normal recording and reproduction mode and said period times 1(1/n) over an integer for frame shot mode. CONSTITUTION:The rotary recording medium 3 is used and a horizontal and a vertical standard scan are made to record or reproduce the TV video signal. The period of rotation of the recording medium 3 is selected by a control signal (e) from a control part 2 to obtain the 1st rotation period which is an integral multiple of the horizontal scanning period of the TV video signal in normal recording and reproduction mode or the 2nd rotation period which is 1/n as great as the 1st rotation period in frame shot mode. A video head 10 is led in parallel to the rotating spindle of a magnetic drum 3 through the rotation of a feed screw 11 while contacting the magnetic surface of the magnetic drum 3. A small hole 17 formed in a pulse plate 16 fixed to the rotating spindle of a leading motor 14, a lamp 18, and a phototransistor 19 constitute a generator for a leading pulse (f) indicating the rotary phase of the motor 14. An actuator 13 displaces the video head 10 in parallel to the rotating spindle of the magnetic drum 3 according to the polarity and level of a tracking control signal (j) supplied from a tracking control circuit (TRC) 23.
