摘要： An air bearing (20) for use on a tape transport apparatus is connectable to an air source (80) and supports a tape (14) on a cushion of air as the tape is transported. The air bearing comprises a housing (22) having an air inlet (34) adapted for connection to the air source and a bearing member (40) disposed on the housing and located so that the tape is transported across a bearing surface. The housing and the bearing member are configured to form a plenum chamber having an interior in fluid communication with the air inlet. At least a portion of the bearing member is fabricated out of a porous material allowing pressurized air in the plenum chamber to pass therethrough and out of the bearing surface to produce the cushion of air. A tape transport apparatus incorporating these features is also provided.

摘要： A recording/reproducing apparatus in which recording/reproducing characteristics for the magnetic tape may be stabilized and data errors may be reliably prevented form occurring. The recording/reproducing apparatus has a magnetic head (81) in which a pair of magnetic core halves (83A, 83B) of a magnetic material are abutted to each other via a gap material ( g ) to form a magnetic core. Magnetic tape guide units (82A, 82B) are provided in the vicinity of the magnetic head (81). The magnetic tape guide units (82A, 82B) are formed with magnetic tape suction openings (82b) closed by a magnetic tape 88 adapted for having a sliding contact with the tape slide surface (82a). The magnetic tape suction openings (82b) suck the magnetic tape (88) running on the tape slide surfaces (82a) of the magnetic tape guide units (82A, 82B).

摘要： A device (1) for carrying out measurements on a thin flexible tape material (6) comprises at least one pair of mutually spaced guide elements (23; 26; 27; 28; 29) which, on adjacent sides, are provided with identical curved guide surfaces (7, 8) which extend substantially parallel to each other, between which surfaces a guide channel (9) for the tape material is formed. In the guide surfaces supply ducts (17) terminate for supplying a pressurized gaseous medium to both sides of a tape material in the guide channel. In the longitudinal direction the tape material can be guided in the guide channel by means of the medium along a curved path which is substantially parallel to and spaced from the guide surfaces. In each of the guide surfaces a termination (22) of at least one measuring duct (21) is situated, the terminations being arranged at least substantially directly opposite each other, in a pair or pairs which measuring ducts communicates with at least one pressure transducer (19) which is connected to measuring means (25). By determining the pressure difference on each side of the tape material with the aid of the measuring means the device enables local tensile stresses in the tape material to be measured.

摘要： A variable width flat tape head for bi-directional contact recording and method for making the same has significant advantages over both traditional contoured tape heads and single width flat heads for contact recording applications. The variable width head and process disclosed herein allows for greater ease of manufacturing, efficient layout of the devices on thin film wafers and provides a significant cost reduction in the production of the head compared to traditionally contoured tape heads. In addition, the present invention reduces unnecessary surface area where the tape contacts the head, thus reducing tape wear and damage that is present in single width flat heads (where the tape is in contact uniformly across the tape width), thereby providing a concomitant improvement in tape wear and life. In addition, the head of the present invention is simpler and less costly to manufacture than comparable devices with distinct advantages to the magnetoresistive ("MR") read element stripe height control process, device alignment and assembly processes particularly with respect to traditionally contoured tape heads, which require more complex and expensive manufacturing operations to form the tape head profile.

摘要： A head (1) of the present invention records/reproduces the information for a tape-shaped recording medium (2). The head has a substantially planar facing surface (4) to the recording medium and an angle (θ 1 ) less than 90° between the facing surface and the lateral surface (5) onto which the recording medium is introduced, so that a multi-channel head and a recording/reproducing head device are provided which can maintain optimum contact with the recording medium and a stable operation even if the recording medium entrance side edge of the head is worn out.

摘要： A helical scan magnetic tape recorder includes a rotary head scanner (50) and an air lubricated bearing magnetic tape guidance system (42),(44),(46),(48) for correcting magnetic tape position errors in a gentle and precise manner without damage to the tape. The magnetic tape guidance system includes several magnetic tape guiding elements (42),(44),(46),(48) including a nonrotatable air lubricated bearing (62), and spaced magnetic tape edge guides (64),(68) for contacting the edges of guided magnetic tape. One of the edge guides (64) is rigidly mounted (66) and the other edge guide (68) is compliantly mounted (70). The rigidly mounted edge guide (64),(66) is adjustable. Any adjustment of the rigid edge guide (64),(66) to change the lateral position of guided magnetic tape is absorbed by the compliantly mounted edge guide (68),(70) without adjustment thereof.

摘要： A tape support which provides several different functions in a reel-to-reel tape drive is disclosed. The tape support provides means for sensing tension in the tape, buffers or decouples the tape at the magnetic head from any perturbations arising at the take-up reel, and reliably guides the tape along the tape path. the tape travels along an arcuate surface of the tape support (16) on an air bearing. A port (17) in the arcuate surface senses pressure between the tape and the arcuate surface. This pressure is communicated to a transducer (22) which provides an output representing the tension on the tape. Flanges (24) on the ends of the tape support provide guiding of the tape over the air bearing and also provide venting of the air bearing to prevent tape vibration. A purge line (28) expels a gaseous medium out of the sense port thereby keeping the sense port clear of contaminants.

The head drum includes a rotary head, a stationary head, and a plurality of magnetic heads for recording and/or reproducing information signals on a magnetic tape. A chamber is provided which includes a first circular recessed portion formed in the rotary drum and a second circular recessed portion formed in the stationary drum. A plurality of grooves are formed in a surface of the rotary drum which communicate between the chamber and the outside of the head drum. The second circular recessed portion is eccentric towards a first position where the magnetic tape starts to wrap about the head drum or it may have a curved recessed portion having a greater depth at the first position than at a second position where the wrapping of the magnetic tape terminates. The recesses are provided to form an uniform air film between the magnetic tape and the head drum in cooperation with the circumambient air introduced therebetween.
