摘要： PROBLEM TO BE SOLVED: To improve the stability of tape running with a simple constitution by arranging a rotating body pivotally supported by a bearing so that its axis of rotation is inclined in the center direction of a tape lead part and forming the center part of the tape lead part to a projecting shape relatively to the track of magnetic head rotation. SOLUTION: A fixed shaft 12 is fixed to a lower fixed drum 11 at a prescribed angle θ to the center of a tape lead part 18 with respect to a reference line Z perpendicularly extended from the center of the lower fixed drum 11 and is inclined with the intersection between a rotation axis Y of a magnetic head 15 and the reference line Z as the center. When the magnetic tape is run, the tape lead part 18 has a projecting shape having a prescribed extent of projection (h) to form the prescribed angle to the track of running of the magnetic head 15, and the fixed shaft 12 is inclined in the center direction of the tape lead part 18. Consequently, the tape doesn't come close to the tape lead part 18 more than necessary on the tape entrance side and exit side of the tape lead part 18, and contact is prevented to stably run the tape.

摘要： PROBLEM TO BE SOLVED: To simplify a structure by eliminating a flying erase head regarding a magnetic recording device. SOLUTION: When a magnetic head traces the same position as that of a track on which digital data is recorded to form a new track and to overwrite digital data, predetermined dummy data is recorded in an unwritten area on which data is not overwritten by the magnetic head, whereby data is completely overwritten on the track on which the digital data is recorded without using the flying erase head. Thus, the structure of the magnetic recording device is simplified by eliminating the flying erase head. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To block the insertion of an information recording cassette by bringing the information recording cassette into contact with a bending reinforcing part when it comes into contact with a cap opening means. SOLUTION: A holder support mechanism is provided with a cassette holder 3 to detachably load a tape cassette 100, and a pair of link connectors arranged at both sides of a cassette entrance and an exit, and adapted to support the cassette holder 3 to move from both sides by the pair of link connectors. The holder support mechanism includes a connection part 19 constituted of a plate body arranged to face the upper surface of the tape cassette 100 to connect the pair of link connectors. In the connection part 19, a bending reinforcing part 20 is disposed by including a part facing a stopper piece and bending a deep side to the tape cassette side, and the insertion of the tape cassette is blocked by bringing the tape cassette into contact with the bending reinforcing part when it comes into contact with the stopper piece.

摘要： PROBLEM TO BE SOLVED: To reduce the manufacturing cost of an upper drum. SOLUTION: The sticking of a magnetic tape 2 to the head drum device 3 by the electrostatic charge is prevented in such a manner that a synthetic resin containing a carbon is used as the material of the upper drum 33. Also, the precision working accuracy is not required for the manufacture of the upper drum 33 by means of forming the outside diameter of the upper drum 33 to be smaller than the outside diameter of a middle drum 32. Thus, the reduction of the manufacturing cost of the upper drum 33 is attained.
