摘要： A tape running guide and tape loading mechanism for magnetic tape recording and reproducing device allows a cylinder drum (10) carrying magnetic heads to minimize its size by employing a three-dimensional loading system is employed in which a level of tape fed to a cylinder drum is made high and that of the tape leaving the cylinder drum is made low. A tape guide system includes, in the tape supply side, at least a first, movable slanted pin (6) and a first, movable tape height regulation guide roller (7) for deriving the tape from an open space of a magnetic tape cassette and winding the tape on the cylinder drum, a second slanted pin (9) and a second tape height regulation guide roller (8) and a third, movable guide pin for winding the tape on the second slanted pin are provided and, in the tape returning side, a fourth, movable slanted pin (13) and a fourth, movable tape height regulation guide roller for deriving the magnetic tape from the open space of the tape cassette and winding the magnetic tape on the cylinder drum, a fifth, movable slanted pin and a pinch roller which are to be derived from the open space of the tape cassette and a capstan arranged outside the open space. These movable tape guide members are movable on a common area in time-shared manner to thereby make the loading mechanism compact.

摘要： A magnetic disk drive that shape coefficient is 3.5 inches are provided, which is designed as rotating magnetic media in a high speed in order to consume a low electric power, to generate a less heat, and to access more quickly.
When magnetic disk media are rotated in a higher speed, an electric power consumption and a heat generation are increased because of a load increase in rotating the magnetic disk media. An avoidance of such problems and setting an additional special cooling mechanism to magnetic disk drive systems, for example, disk array systems, is presented.
A housing 11 of magnetic disk drive in a shape coefficient 3.5 inches mounts magnetic disk media 21 for a magnetic disk drive in a shape coefficient 2.5 inches, which aims a lightweighting of a rotational spindle portion, a decrease of a torque loss during on-load rotation with the media, and a decrease of a electric current into a spindle motor 41 during rotation.
Further, fins 11a for heat radiation may be arranged around the housing 11, which results in avoidance or decrease raising a temperature in the housing 11.

摘要： A slide type cassette loading apparatus includes a loading section (20) for receiving a tape cassette (31) to move the same between an inlet/outlet position and a reference position for loading, and a movable chassis (3) for sliding the cassette, located in the reference position, to a recording/reproducing position while carrying the cassette on the movable chassis. The loading section (20) is of a double structure type which has an outer cassette holder (5) pivotable relative to the movable chassis (3) and an inner cassette holder (4) supported to the outer cassette holder (5). The inner cassette holder (4) is mounted on the outer cassette holder (5) so as to make a pivotal movement together with the outer cassette holder (5) and be movable in slide directions of the cassette (31), and is operatively coupled to the movable chassis (3) so as to be movable together with the movable chassis (3).
