摘要： 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.

摘要： 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.

摘要： 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.

摘要： PURPOSE:To selectively use two kinds of large and small tape cassettes and to miniaturize a device by a simple constitution. CONSTITUTION:There is a large tape cassette 1 which shares with a small tape cassette 12 in one recording and reproducing device 22; and when the center of the front of this large tape cassete 1 is overlapped on that of the small tape cassette, two tape exits 3 and 3' on the entrance side and the exit side are placed in positions approximately equal to two tape exits 14 and 14' of the small tape cassette. Two leading-out guides 27 and 27' on the tape suppy side and the tape take-up side are provided which lead out a recording medium tape 5 (16) from a cassette case 2 (13) and are used as tape guides at the time of running of the recording medium tape. While the tape is run, these two leading-out guides are placed in the same position at the time of using the large tape cassette as well as the small tape cassette.
