    Abstract: PROBLEM TO BE SOLVED: To facilitate retrieval of an image of a queue review and to attain high speed dubbing in the case of reproducing data of a variable bit rate by a method such as the MPEG 2 in the helical scanning recording and reproducing device that records data of a computer or the like on a tape medium by helical scanning. SOLUTION: In a helical scanning recording and reproducing device 6 in which a difference between a recording rate and a data transfer speed is eliminated through intermittent drive of a tape and the utilizing efficiency of the tape is improved, data are continuously reproduced at a constant speed without intermittent reproduction in the case of reproduction of the MPEG 2 queue. In the case of dubbing, data are continuously reproduced at a constant speed without adopting intermittent tape feed. A reproduction data storage section made up of a hard disk unit or the like to store just preceding reproduction data is provided in a buffer section 62, and a review image is displayed by using reproduction data stored in the reproduction data storage section in the case of a review.

    Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a recording tape and to improve the wear resistance of a reproducing head by stopping the recording tape while keeping the holding of a tape sending mechanism and performing an operation for slackening the tape. SOLUTION: When shifting to a standby mode, a control means controls a tape sending mechanism so as stop a a recording tape 308 whole the tape 308 is held between a pinch roller 4 and a capstan 3. By controlling a tension regulator mechanism, a locking piece 11 on a chassis 1 for locking one end of a tension regulator spring 12 is moved to a tension regulator arm 5 and by reducing the expansion of the tension regulator spring 12, the tension of a band brake 10 is reduced. Thus, the reproducing device is provided, wherein a contact force between the recording tape 308 and a rotary head 2 is weakened, the damage of the recording tape 308 is prevented and the resistance of the rotary head 2 is improved.

    Abstract: PURPOSE: To prevent a magnetic tape from being tightly stretched with excessively strong tension by constituting a recording and reproducing device so that an electrical tension regulator can control the tension of the magnetic tape on the downstream side of a capstan. CONSTITUTION: A control circuit 60 is constituted of, for example, a one-chip type microcomputer, provided with, for example, a four-bit parallel processing arithmetic processor (CPU), storage device (RAM) in which a prescribed program is written, in advance, input-output interface which controls the input and output of signals, etc., and performs prescribed arithmetic processing based on signals inputted from A/D converters 57 and 58. Since the circuit 60 adjusts the voltage applied across a reel motor 20 by controlling the output of the circuit 60 based on the processed results, the tension of a magnetic tape is maintained at a fixed value on the downstream side of a capstan 13.

    Abstract: PURPOSE: To perform fast forward(FF) and rewind(REW) of a tape without any possibility of damaging the tape and only by a tape guide without winding the tape around a rotary drum even when excessive tension is applied to a tape guide during loading. CONSTITUTION: A control pin 38 is provided in a tension arm 30 and a stopper arm 40 is also provided so as to be relatively rotated with the tension arm 30. The stopper arm 40 is provided with an elastic body 44 positioned in the pulling out side of the control pin in its moving direction and a stopper wall oppositely placed so as to hold the control pin 30 while keeping a prescribed interval with the elastic body 44. By restricting the moving range of the control pin 30 by the elastic body 44 and the stopper wall, the rotating range of the tension arm 30 is controlled by the stopper arm 40.

    Abstract: PURPOSE:To evade hindrance to a tape loading operation by releasing turning restriction on a supply side tape reel and drawing out a tape from the supply side in place of a take-up side tape reel. CONSTITUTION:When the beginning of the tape T drawn out of the take-up side tape reel 2 is detected by a photodetector part 22, this drawing operation is stopped. Then, when the beginning of the tape is not detected, tape loading is completed, and turning regulation of a reel base 17 is released to make the supply side tape reel 1 turnable, and a pinch roller 15 is moved to a capstan 13 to hold the tape T between them. Then, the tape T is traveled via a rotary head cylinder 12 from the reel 1 to 2 or the reel 2 to 1. Then, when the tape is directed from the reel 1 to 2, a recording operation, a reproducing operation and a fast forward reproducing operation, etc., are performed, and when the tape is directed from the reel 2 to 1, a rewinding reproducing operation, etc., are performed. Upon completion of these operations, the tape T is taken up in synchronization with movement of movable guide posts G1-G8 to their unloading positions after regulating turning of the reel base 17.
