摘要： PROBLEM TO BE SOLVED: To reduce the assembly manhour by preventing a backlash with an inexpensive configuration (using an inexpensive part), obtaining a stabilized pressurizing power and making the cost low. SOLUTION: The backlash prevention mechanism used for a head feed mechanism (40) which moves a head assembly (30) up and down along the axis direction extending upward and downward is means to constantly push a head lift (42) in one direction along the central axis of rotation of a lead screw (41). A preload bush (43) is arranged inside an opening hollowed inside (42a) and has a groove (431) which is in a rotating engagement with the lead screw. A compression coil spring (48) is arranged between the preload bush and the lead bush in the opening hollowed inside and provides the head screw with the pushing power in the axis direction of the head screw. And, the groove of the preload bush (43) deviates a half pitch from the groove (471) of a vertical motion member (47).

摘要： The encoding device includes signal affixing appts., for affixing each time an m-bit digital word, where m is equal to 1, to a consecutive n-bit information word to obtain an (n+1)-bit information word. The aT precoder is arranged for converting the (n+1)-bit information words into (n+1)-bit channel words. The encoding device further includes a control signal generator which is arranged for receiving the (n+1)-bit channel words from the aT precoder and for deriving a control signal from the (n+1)-bit channel words. The signal affixing appts. affixes a 1-bit digital word to an n-bit information word in response to the control signal. The running digital sum value in the output signal of the precoder plotted against time shows behaviour according to a desired pattern.

摘要： PROBLEM TO BE SOLVED: To reduce the number of assembling process and to enhance the productivity and also to reduce the manufacturing cost by providing a head position adjusting member of an adhesive capable of arbitrarily adjusting a head position between the fitting member and the position of a magnetic head for a movable head device that is not mounted with the magnetic head yet. SOLUTION: A DT head device assembled in the state before fitting a magnetic head 142 is fixed on a rotary drum 120 and the appropriate amt. of an adhesive 144a is applied on the tip of a bimorph 141 of this head device. The magnetic head 142 fitting a reinforcing plate 146 of a flexible printed circuit board 145 is placed on the adhesive and the head height, the angle division and the protrusion, etc., are adjusted while observing the head 142 by a microscope, etc. While the accurately positionally adjusted magnetic head 142 is held in its posture, the adhesive 144a is cured by irradiation of ultraviolet rays and is fitted to the tip of the bimorph 141 via an adhesive layer 144. Consequently, the productivity and yield are enhanced without necessity of ranking the head height.

摘要： PROBLEM TO BE SOLVED: To obtain excellent electromagnetic conversion characteristics while controlling optimum tracking by joining members with a UV curing resin while each member is maintained in an optimum state. SOLUTION: Fitrs, a bimorph plate 3 is joined with a parallel leaf spring 7. Then the UV curing resin 8 is applied on the interface between the bimorph plate 3 and the leaf spring 7. The UV curing resin 8 has 1.2 to 1.6MPa Young's modules so that it does not give strong tension to each member untill the resin is cured. Therefore, by using the UV curing resin 8 as an adhesive to join the members, the members can be joined without changing the position of each member. The bimorph plate 3 and the leaf spring 7 coated with the UV curing resin 8 are put in a UV curing furnace and irradiated with UV rays.
