摘要： A magnetic recording and reproducing apparatus of rotary head type such as a rotatable video tape recorder has a tape guide for guiding the magnetic tape when the tape runs on and around a cylinder carrying rotary heads. A tape loading movable member carries the tape guide. A tape loading drive is provided for driving the tape loading movable member so as to move the tape guide between a tape loading position where it places the magnetic tape in contact with the cylinder through a predetermined angle and an unloading position where it keeps the magnetic tape away from the cylinder. A locating unit is provided on at least one of the cylinder and a cylinder base carrying the cylinder. The locating unit is adapted for engaging with the tape loading movable member in the tape loading position so as to locate the tape guide with respect to the cylinder. The tape loading drive drives the tape loading movable member by making use of the mechanical motion of a cassette holder for mounting the cassette on a predetermined portion of the apparatus.

摘要： The present invention relates to a magnetic recording and reproducing device wherein reproduction monitoring can be made directly after recording, and more particularly to a construction of a rotary drum for the same. The magnetic recording and reproducing device includes a single recording channel for n recording magnetic heads, and n reproducing channels for n reproducing magnetic heads. The recording channel is provided either on an innermost circumference side or on an outermost circumference side of a rotary transformer. Since the device has such a reduced number of recording channels, the distance between adjacent channels can be increased and the transmission loss of a reproduction signal can be reduced.

摘要： As a method of increasing the storage capacity of a magnetic recording and reproducing apparatus for recording and reproducing information to and from a magnetic tape in a cartridge, there is a helical scan recording method in which the magnetic tape is diagonally wound around a drum which rotates a magnetic head. With an apparatus adapted to this method, the disposition of the cartridge and the take-up reel for taking up the magnetic tape on the same plane arises a necessity of considerably bending the magnetic tape at the drum portion and, accordingly, the magnetic tape is damaged. In order to prevent the damage of the foregoing type, the tape passage surface from the cartridge to the drum and the tape passage from the drum to the take-up reel are formed by an angle at which the direction in which the magnetic tape is moved is changed due to winding of the magnetic tape around the drum so that the magnetic tape is not bent excessively. A threading device capable of three-dimensionally controlling the position of the magnetic tape in accordance with a predetermined tape passage is provided for the apparatus structured as described above. The threading device is formed by a link mechanism to be moved along the locus of a cam groove so that the three-dimensional position control can be performed.

摘要： A tape run control unit in a magnetic recording and reproducing apparatus is provided with a discriminator and on a controller. The discriminator detects a stand-by time until a signal to be recorded is received in repositioning of the tape and generates a discrimination signal for discriminating the length of the stand-by time. The controller controls tape driving unit such as a capstan motor during the reposition and controls the stop position of the tape such that a magnetic head scans the portion of the tape where no data is recorded. After completion of repositioning, furthermore, the controller is responsive to a discrimination signal so as to select the stop mode which involves the release of pinch roller when the stand-by time is long and to select the mode for simply stopping only the capstan when the stand-by time is short.

摘要： An optical recording and reproducing system has an optical recording and reproducing head driving arrangement including an optical pick-up and has an optical recording medium provided between the recording heads. The optical recording and reproducing head is mounted on a rotating arrangement. The head scans tracks while a relative position of the recording medium and rotating arrangement is changed. Each track has an address recorded at the beginning of scanning and a hold signal at the end of scanning. The recording and reproducing heads are separated one track. The recording head makes recording while the reproducing head makes reproduction. In the recording or reproducing mode of operation, the track address is looked. If wrong, it is corrected. The hold signal is detected to operate a tracking device and focusing device. Scanning the next track is determined by the address before tracking is made for recording or reproduction.

摘要： A tape guide device having apertures formed in two tape-winding surfaces of non-rotatable curvature portions. A tape restriction is provided at a connecting portion of the tape guide device interconnecting the curvature portions. A flange is provided on one of the curvature portions for movement along an axis thereof to adjust the height thereof. The flange has an outer diameter greater than that of the one curvature portion. The curvature portions are integrated with each other. According this, an air film is generated between the tape and the tape-winding surfaces by discharging air from the apertures, thereby reducing the friction coefficient between the tape and the tape-winding surfaces to suppress the increase of tape tension. The tape is restricted to fluctuate in the direction of width. Further, the attitude and relative positioning between the curvature portions can be secured with high precision. As a result, the tape load during the tape running is reduced, thereby stabilizing the tape running and prolonging the lifetime of the tape.
