Abstract: A tracking control arrangement for a video tape recorder effects simultaneous recording and then simultaneous reproduction of four channel recording tracks (TRa, TRb, TRc, TRd) formed on a magnetic tape (2) under tracking control effected by detecting tracking error in dependence on the phase difference between reproduced signals from two adjacent recording tracks (TRc, TRd) of the four at the time of reproduction, the adjacent two recording tracks (TRc, TRd) being recorded with different azimuth angles. A signal delayed by a delay circuit (100) with respect to the signal recorded in one (TRd) of the two adjacent recording tracks is recorded in the other one (TRc) of the two adjacent recording tracks, thereby permitting tracking control by bimorph plate (3A, 3B) or capstan servo control (106) in dependence on the phase difference between the reproduced signals produced from two magnetic heads (1C, 1D) corresponding to the two adjacent recording tracks (TRc, TRd).

Abstract: A helical scan-type magnetic recording and reproducing apparatus adapted to VTR or DAT. This apparatus includes a head scanning mechanism which helically scans the tape (3) that runs in parallel with a reference plane using a head (4) that turns in a slit (5) that meets aslantly with the drum shaft (6) between the upper and lower fixed drums (2) and (1) arranged perpendicularly with respect to the reference plane. This mechanism consists of a rotary member (30) in concentric with the upper and lower fixed drums (2) and (1), a linear guide (10) or (31) provided for the rotary member (30) to slide in a direction in parallel with the center of rotation of the rotary member near the head, a head (4) provided for the linear guide (10) or (31), and a cam mechanism (16) or (32) which gives axial displacement to the head (4) in the same direction as the slit (5) relative to the stationary cylindrical members (1), (2), (40). The head (4) is turned by the rotary member (3) and is, at the same time, linearly moved back and forth in the direction of the width of tape smoothly and stably.

Abstract: 57 A method for recording and reproducing information signals with a magnetic tape which is helically scanned with a rotary recording and reproducing head in which, upon reproducing, it can readily be determined whether the content of the tape is recorded in the ATR mode or the VTR mode. A series of information signals and an identification signal are recorded in a plurality of respective areas formed by dividing the tape in a crosswise direction thereof. For reproduction, the series of signals recorded at each of these areas is reproduced only when the identification signal is detected.

Abstract: A method and device for storing and accessing information on a flat storage medium (116) having X and Y axes. A read/write head (120a) is positioned adjacent to the medium and an X-axis motor (108-109) creates a reciprocating substantially linear motion between the head and the medium along the X-axis of the medium. A Y-axis motor (112) creates a linear motion between the head and the medium along the Y-axis of the medium. The head causes information to be stored or accessed on the medium as the head moves across the X-axis of the medium. The relative substantially linear motion of the head along the Y-axis moves the head from track to track along the medium. The relative motion between the head and the medium can be created by moving either the head or the medium.

Abstract: A rotary head apparatus, which is employed in a video tape recorder and has a dynamic pressure-type fluid bearing, is provided with cylindrical rotary transformers (31, 32) which are coaxial with a fixed shaft (22), thereby to reduce the size of the apparatus. Moreover, of the two herringbone groups (26A, 26B) provided on the fixed shaft (22), the group (26A) closer to the free end is made larger in size than the one closer to the fixed end, thereby giving a stable rotational performance even when the apparatus is inclined.

Abstract: A rotary head assembly has a rotary member (14) on which is mounted a magnetic head (23) in a gap between upper and lower stationary cylinders (17, 18) arranged on the same shaft and of substantially equal diameter, and the rotary member is rotated to feed a magnetic tape which is helically wound on the outer peripheral surfaces of the upper and lower stationary cylinders (17, 18). The cylinders (17, 18) are fixedly supported by a stationary shaft (12) arranged on the same axis as the cylinders (17, 18), facilitating precise assembly, reducing the power consumption, and more stable feeding of the magnetic tape.

Abstract: A rotary head apparatus, which is employed in a video tape recorder or the like and has a dynamic pressure-type fluid bearing, is provided with a plurality of pairs of cylindrical rotary transformers (31A, 31B, 32A, 32B) which are coaxial with a rotary shaft (22), thereby to reduce the size of the apparatus. Further, of the two herringbone groups (26A, 26B) provided on either the rotary shaft (22) or a sleeve (21a) or both, the group (26A) closer to the upper cylinder is made larger in size than the one closer to a motor, thereby giving stable rotational performance even when the apparatus is inclined.
