    摘要: High performance is obtained without preventing achievement of a target read data rate.In a controller 16 of a tape drive, a command processing unit 41 receives a synchronization command, and a buffer management unit 42 passes data in a buffer to a channel input-output unit 43. Then, upon completion of writing the data to the tape, a backhitch determination unit 44 determines whether or not to execute backhitch. If it is determined that backhitch should be skipped, the speed determination unit 46 determines a tape speed that minimizes a sum of a time required to write data without backhitch within a range where a data amount of a monitor target is to be written in order to achieve a target read data rate, and a time required to write data with backhitch within the range. Then, an operation signal output unit 49 issues an instruction to change the tape speed to the determined tape speed after execution of backhitch.

    摘要: Dynamic tension control for tape transported along a tape path between supply and take-up reels, driven by supply and take-up motors, and having tachometers for determining linear speed of the tape. A controller accelerates the tape toward a target speed, initially operating the motors in static acceleration tension control; and if the linear speed of the tape is within a predetermined range of the target tape speed, operating the motors in composite tension control employing static tension control and delta velocity control.

    摘要: A tape recorder which includes an automatic reversing mechanism and wherein fast feeding or rewinding of a tape started manually is ended by releasing an operating member therefor from an actuated arrested position when the tape comes to its end is improved in operability with a simplified construction at a reduced cost. The tape recorder comprises a trigger member for mechanically detecting stopping of a reel receiving member to activate a tape feeding direction change-over mechansim, a pair of operating members manually operable for initiating a fast feeding or a rewinding operation, an arresting mechanism operable for arresting an actuated operating member to its actuated position, a transmission member operable in response to the actuated operating member for operating the trigger member, and a tape feeding direction change-over member mounted for engagement by the operating members. When a tape comes to its end while one of the operating members is arrested to its actuated position, the trigger member urges the transmission member to release the operating member from its arrested position.

    摘要: A mechanism for switching pinch rollers of an autoreverse car audio device has a mode changing lever actuated by a driving motor. The mode changing lever causes a rotation of a switching lever movably installed at a rear face of a deck frame. One end of the switching lever is engaged with one end of a pinch roller selecting plate for selecting one of pinch rollers according to an operation mode. The pinch roller selecting plate is actuated relative with the switching lever rotated according to the operation mode. Therefore, one of the pinch rollers approaches a corresponding turntable wheel.

    摘要: An automatic reversible tape recorder is disclosed in which the functions of the keys for fast forward and rewinding are improved, and the manufacturing and assembling are rendered easier owing to the simple structure of the components. The tape recorder includes first and second manipulation levers 110 and 120 capable of moving back and forth horizontally to make said magnetic head ascend or descend, upon completion of displacements of a certain distance. The tape recorder further includes a locking member 130 for selectively fixing said first and second manipulation levers 110 and 120 upon ascending of said magnetic head due to advancement of said first and second manipulation levers 110 and 120. The tape recorder further includes a tape running direction reversing member 140 installed coaxially with said locking member 130, for being turned as much as a certain amount of angle upon advancing of said second manipulation lever 120, so as to push a program lever 150 (which pushes a cam gear). In the present invention, the functions of FF and REW are improved, and the mentioned functions are carried out in a simple manner. Further, the manufacture and assembling of the tape recorder become easier. Further owing to the simple constitution of the direction reversing member, the price of the tape recorder can be lowered.
