摘要： In a digital recording and reproducing apparatus, as for the recording system, a high-efficiency coded bit stream is inputted from the input terminal to a search-data generating circuit where at least two kinds (low speed and high speed) of low-bit-rate bit streams for special playback are produced from the input bit stream and the produced data is recorded in a multiple manner. As for the reproducing system, the at least two kinds of low-bit-rate bit streams which were generated during recording are reproduced and decoded, whereby at least two kinds of search speeds can be selected.

摘要： In a digital VTR which is able to record a band-compressed signal having a bit-rate of 17 to 60 Mbps of a program while creating a low-bit-rate signal (1.5 to 5 Mbps) having the same program content as well as utilizing the low-bit-rate signal as a signal for the special playback, the present invention proposes two method. A first method is that variable-speed playback data for a certain speed, which is recorded in the limited recording areas for variable-speed playback mode, is adapted to be used for playback at another speed in the variable-speed playback mode. A second method is that data structure of variable-speed playback data is adapted to change depending on the image areas on the image frame. Either of the above methods or the combination of them improves the digital recording and reproducing apparatus in its quality of picture at the variable-speed playback mode in which a less amount of data is available than that of data read out at the time of the normal playback mode.
摘要翻译：在能够记录具有程序的17至60Mbps的比特率的频带压缩信号的数字VTR中，同时创建具有相同节目内容的低比特率信号（1.5至5Mbps），以及利用低比特率信号作为特殊重放的信号，本发明提出了两种方法。第一种方法是将用于可变速度重放模式的受限记录区域中记录的一定速度的可变速度重放数据适用于在可变速度重放模式中以另一速度重放。第二种方法是可变速重放数据的数据结构适于根据图像帧上的图像区域而改变。上述方法之一或它们的组合在数字记录和再现装置的可变速度重放模式下改善数字记录和再现装置，其中数据量比在正常时间读出的数据的数据量少播放模式。

摘要： A head carrier drum assembly in a magnetic tape recording and/or reproducing apparatus, which assembly comprises rotary and stationary drums of equal outer diameter, the rotary drum (6) being mounted on a drive shaft (2) for rotation together therewith while the stationary drum has a cylindrical center sleeve (1a) integral therewith and extending in coaxial relation with the drive shaft around the drive shaft through at least two spaced apart radial bearings (3, 3'), at least one magnetic transducing head (5) carried by the one of the rotary drum for rotation together therewith, and a rotary transformer (16) including cylindrical rotary (23) and stator (24) cores for electrically interfacing between the magnetic transducing head and an external electric circuit. The radial bearings are interposed between an outer peripheral surface of the drive shaft and an inner peripheral surface of the sleeve. The cylindrical stator core of the rotary transformer is fitted to the inner peripheral surface of the sleeve while extending between the radial bearings and the cylindrical rotor core of the rotary transformer is mounted direct on the peripheral surface of the drive shaft in face-to-face relationship with the stator core.

摘要： A magnetic recording and reproducing apparatus which includes a set of loading members (27, 28) for drawing out a magnetic tape accommodated in a tape cassette and wound around a set of reels disposed to contact the same plane, from tape storing portions (25, 26) of the tape cassette so as to be directed along part of the outer peripheral surface of a rotary head cylinder (14) in an approximately M-shape, and a single inclining member (8) provided in the vicinity of one tape storing portion (25) for causing a tape travelling reference face of the magnetic tape drawn out from the tape storing portion (25) to be inclined. The first loading member (27) corresponding to the tape storing portion (25) is rotatably supported at right angles with respect to the tape travelling reference face of the magnetic tape inclined by the inclining member (8), while the other loading member (28) corresponding to the other tape storing portion (26) is rotatably supported at right angles with respect to the tape travelling reference face (33) of the magnetic tape drawn out from the other tape storing portion (26).
