Title: Brake device on reel bases
Inventor: KUROKAWA TOSHIYA
IPC: G11B15/22
Filed: 1992-12-03
Abstract: PURPOSE:To reduce the number of parts for the brake device on the reel bases and to miniaturize the device main body. CONSTITUTION:One pair of reel bases 70 and 71 is arranged in a VTR. A brake 5 is arranged opposite to one reel base 70. At the time of loading and also at the time of unloading, the reel base 70 is regulated in its rotation by a control mechanism (1-4, 7 and 21) with the brake 5. When the feed of a tape from the other reel base 71 is regulated by a tape top at the time of loading, the tape is fed from the reel base 70 without regulating the rotation of the reel base 70 by the brake 5 even at the time of loading. Braking the reel bases can be controlled only by arranging the brake opposite to one reel base. Consequently, the brake mechanism can be simplified by reducing the number of parts for the brake device on the reel bases, so that the device can be manufactured at low cost, and the device main body can be miniaturized by saving space.

Title: Video signal recording method
Inventor: NISHIMURA KEIZO
IPC: G11B5/027
Filed: 1992-12-04
Abstract: PURPOSE:To prevent the deterioration of the reproduced picture quality even at the time of being unreproducible due to one hard having clogging by recording successively the video signals in the unit of each divided block and also arranging these video signals on the tracks in the order different from the line numbers order. CONSTITUTION:When the video signals of 525 lines per frame are recorded and reproduced, the signals of a single field are divided input four tracks and recorded. If a head B has the clogging among those four heads, the tracks 2 and 6 become unreproducible. At the same time, the lines 7-259 become unreproducible in a N-th field and the lines 269-521 become unreproducible in a (N+1)th field respectively. Thus these unreproducible lines are discrete from each other. Viewed at every field, one of four lines becomes an unreprodicuble noise signal. In this respect, the front area of an unreproducible line is replaced with the average value before and after the unreproducible line by employing the line correlation characteristic of the image signal. Thus the unreproducible lines can be compensated with each other and the occurrence of noises can be suppressed on a screen.
