摘要： Pneumatically controlled apparatus (10) serves jointly for automatically threading magnetic tape (16) along a transport path past a magnetic transducer head (26) external to a magnetic tape cassette (60), then transporting the tape along such path. Tape transport elements of the pneumatic-type-air-bearing guides (28a, 28b, 52, 54), a vacuum capstan (55a, 55b), etc. are arranged, like the magnetic head, on the oxide surface side (the information-bearing surface) of the magnetic tape. To thread the tape, a vacuum source (22) provides an air pressure gradient the effect of which is to draw tape, spanning a supply reel (18) and a take-up reel (20), from the cassette in the form of an expandable loop which takes the shape of the transport path when the tape loop expands into operative engagement with each transport element and the transducer head. The air-bearing guides (28a, 28b) are disposed immediately adjacent and tangential to opposing sides of the transducer head. The vacuum source, in cooperation with each air-bearing guide, provides the same air pressure gradient, used to thread the tape, to draw, and to thereby maintain, the tape adjacent the tape-guiding surface of each air-bearing guide during movement of the tape between the supply reel and the take-up reel.

摘要： A helical scan magnetic tape recorder (1) includes a rotary magnetic head scanner (11) and a received magnetic tape cassette (2) including spaced coplanar supply and take-up reels (3, 4) having magnetic tape (30) spooled on the reels (3, 4) with a span (7a) of magnetic tape (30) extending between the reels (3, 4). Supply and take-up vacuum cavities (9, 10) are located contiguous to and on respective opposite sides of the scanner (11). Supply and take-up capstans (12, 13) are spaced from the rotary head scanner (11) located in a tape transport path between the vacuum cavities (9, 10) and the tape cassette (2). Magnetic tape (30) is initially removed from the cassette (2) and moved to a tape vacuum loading position where it partially contacts the rotary head scanner (11), by a mechanical threading device (5, 6). Thereafter, vacuum is applied to the vacuum cavities (9, 10) to draw the tape (30) into contact with the vacuum cavities (9, 10) to substantially wrap the tape around the rotary head scanner (11). The supply and take-up capstans (12, 13) are rotated during vacuum threading to assist drawing the tape into the vacuum cavities (9, 10).

摘要： A helical scan magnetic tape recorder has a magnetic tape threading and guiding system. Magnetic tape (26) contained in a cassette (20) is extracted from the cassette (20) and threaded around a magnetic tape path past a helical scan magnetic head assembly (14) by means of a pneumatic threading arrangement (74, 76, 78, 80). Tape threading is fast and gentle with no stress or edge damage to the tape. The threading arrangement has relatively few moving parts and is simple and reliable in design. After the tape is threaded into the tape transport, a plurality of tape guide elements (52, 54, 56, 58, 66, 70, 72, 80) mounted on a precision platform (100) are moved into position behind the magnetic tape (26). Thereafter, the pneumatic threading vacuum is terminated and the magnetic tape (26) is tensioned around the guide elements (52, 54, 56, 58, 66, 70, 72, 80) which establish a low constraint tape path about several stationary magnetic head assemblies (40, 42, 44) and a helical scan head assembly (14).

摘要： A helical scan magnetic tape recorder (1) includes tape threading and guiding apparatus for threading magnetic tape (30) from a two reel cassette (2) about a rotary magnetic head scanner (11) and for tensioning the tape (30) during tape transport. The threading and guiding apparatus includes supply and take-up compliance elements (5, 6) which are mounted for movement between: 1) cassette loading positions behind a tape span (7a) in a magnetic tape cassette; 2) tape vacuum loading positions (5a, 6a) in which the elements (5, 6) draw tape (30) out of the cassette (2) and partially contact it with the rotary head scanner (11); and 3) operating positions (5b, 6b) in which the elements (5, 6) draw tape (30) around the respective supply and take-up capstans (12, 13) and tension the tape (30) during tape transport past the rotary head scanner (11).

摘要： Helical scan tape recorder/playback apparatus (10) includes a pair of concave air-bearing surfaces (28a, 28b) disposed immediately adjacent and tangential to opposing sides of a circumferential surface of a rotary head scanner (14), to cooperatively form a path for guiding magnetic tape (16) past the head scanner at a predetermined angle (a) other than zero degrees. A vacuum source (22) serves to evacuate air from the vicinity of each air-bearing surface to create an air pressure gradient the effect of which is to cause magnetic tape to ride on a thin film of air interposed between the tape and each air-bearing surface during transport of the tape from a supply reel (18) to a take-up reel (20).

摘要： A tape guide mechanism includes an edge-guide element (42) extending radially from a central axis. A tape guide roller (14), rotatable about the central axis, is arranged for urging an advancing magnetic tape laterally in the direction of the edge-guide element, to maintain an edge of the tape perpendicular to and in continuous contact with the edge-guide element during tape transport movement. A piezoelectric actuator (51), preferably comprising a stack of flexing type bimorph elements (52) responsive to a voltage signal relating to the direction and magnitude of a tape-tracking error, causes movement of the edge-guide element (42) in a single composite direction having a first component which is perpendicular to the edge of the tape, and a second component, which is parallel to the tape edge. Thus, the tape is caused to move laterally in either direction for tracking control, in one direction under the influence of perpendicular movement of the edge-guide element (42) toward the tape, and in the opposite direction under the urging of the guide roller (14), to follow perpendicular movement of the edge-guide element (42) away from the tape.

摘要： Magneto-optic transducer apparatus of a rotating form reads high-frequency information recorded on a magnetic tape (18) in other than a longitudinal format. To read information recorded in a slant track format, the transducer apparatus includes a first optical fiber (41) for scanning a polarized light beam (46) along a path adjacent the tape from one tape edge towards the other edge during the transporting of the tape. A magneto-optic element (55) is arranged in the path of the light beam adjacent the tape, to modulate the light according to magnetization of the region of the tape adjacent the magneto-optic element as the light beam is scanned across the tape. A second optical fiber (42), optically coupled to the element (55), directs the modulated light to impinge on light-responsive apparatus (52, 58), which is arranged to produce an electrical signal that is functionnally related to the modulation of the light.
