Description

DETAILED DESCRIPTION OF THE INVENTION                  Tape support system for arcuate scanning rotary head                                Background of the Invention Field of the invention   The present invention relates to a rotary transducer drum end of an arcuate scan head assembly (ASHA). Method and apparatus for selectively contacting a transducer on a surface with a magnetic tape, and recording Between the head and tape, especially at the edge of the tape It relates to a tape support system for perfect adhesion. Description of related technology   Many commercially available magnetic tape drive systems have a substantially fixed read / write head. To transport the magnetic tape that has passed through the I use it. Usually, the information is in a number of parallel tracks that extend along the longitudinal axis of the tape. Recorded on the tape. A fixed read / write head can be used for single or multiple channels. Can have The read / write head reads different tracks on the tape It can move laterally to read, but during a read / write operation, the head Qualitatively fixed. For recording and playback, the tape in the area previously read / written This is achieved by moving Since the read / write head is fixed, the head and It is relatively well known that good contact with the pump. For example, tape on the head Can be wound.   Another widely used tape drive is one in which one or more heads are rotated serially. Using a vertical helical scan (VHS) head located outside of the drum or drum . The tape is partially wrapped around the cylinder surface while the cylinder Move the side. The cylinder is tilted with respect to the tape path, so each The head follows the spiral path along the tape. Furthermore, Contact between the head and the tape partially wraps the tape around the side of the cylinder. It is easily maintained by swaging.   Newly developed arcuate scanning tape drive (International Application W O 93/26005) is a transducer that contacts the tape surface when the tape moves. And a rotary transducer drum having a substantially planar end face comprising: VHS drive In contrast to the device, the axis of rotation of the transducer drum passes through the tape surface. Therefore, that Each transducer reads a series of arcuate tracks across the tape in a generally horizontal direction. Because of this, it is called an arcuate scan head assembly, or ASHA.   Using ASHA to wrap the tape around the end face of the drum is a conversion Means that the container is in continuous contact with the tape along the complete conversion path . Such a configuration accelerates wear of the tape and the read / write head. Change During the part of the path facing the recording area traced by the transducer, / Even if the writing head is turned off, the head contacts the tape Then, a crosstalk signal which causes system noise is generated.   The front face of the transducer drum in contact with the tape surface is approximately 7,500 to 15,000. Rotate between 0 rpm. It may be used faster in the future. Drum end If the face is inserted into the tape face, the rotation of the transducer drum with respect to the tape face is A drag that is substantially perpendicular to the vertical axis of the loop is generated. In particular, the opposing edges of the drum One edge of the rotating drum is aligned with the vertical axis of the tape while the Producing crossing forces tends to twist the tape in the direction of drum rotation . Therefore, in particular, it is difficult to bring the head and the tape into close contact at the edge of the tape. Extremely difficult.   In addition, the transducer typically has a slight, e.g. 0 005 inches (0. 0127 mm).

And a method for contacting the same. Transducer on tape surface along read / write section Describes many tape support systems for positioning tapes to penetrate I do.   For a successful bow scan recording system, the head and tape should be It is necessary that they match. End face of transducer drum penetrates tape surface Therefore, the change in longitudinal tension across the web in the read / write area is particularly At the edge, it causes an enlarged change in the reproduced signal. Therefore, read / write head It is important that the tape enter the tape exactly.   The degree of tape tension (force per unit tape deviation) against head intrusion is Usually, the edge of the tape is smaller than the center. Various tapes disclosed herein The support system is taped to optimize the contact between the transducer and the tape edge. Designed to regulate power. Controls the tape tension in the read / write section One way to do this is to form multiple bends in the tape. For details, Bend in both the vertical and horizontal directions to provide semi-rigidity to the tape where the bends intersect. Give it. Lateral and longitudinal bends are made with the various tape support structures described here. It is.   An arcuate scanning tape drive has a rotating end surface including at least one transducer. A type converter carrier can be provided. Transducer enters tape at read / write section I do. The end face bends the tape first closest to the read / write section. Read / The tape support system in the vicinity of the writer was first bent at the reader / writer Make a second orthogonal bend across. When the first and second bends intersect, read / write The tension or tension of the tape at the insertion portion increases. Tape support system Can be located adjacent to the transducer carrier or on the end face.   The embodiments disclosed herein are directed to general tape to arcuate scanning tape drives. The elements of the whole support system are shown and can be freely combined. In the figure The size of the tape, transducer, and drum angle and movement make the description easier to understand Shows quite exaggerated for. For example, a typical converter is a 0. 0015 (0. 0381 mm) and preferably less than 0. 0005 inches (0. 0127 mm) and 0. 001 inch (0. 0254mm) and tape Penetrate the surface.   FIG. 1 shows a rotary head transducer 20 having a pair of tape support arms 22 and 24. It is a side view. The tape support arm 22 (passive support arm) is a tape support arm. Slightly longer than the arm 24 (active support arm), Between the portion of the end face 30 of the transducer drum 32 closest to the holding arm 22 and the tape 28 Occurs. Therefore, the rotary transducer 34 is a read / write section of a generally circular transducer path. It will only contact tape 28 along 36 (see FIGS. 4 and 5). Isolation area Due to the presence of 26, transducer 34 is out of contact with tape 28 and The passive segment 38 of the road is used to polish the head and tape in this area. Wear is thus limited.   The reference surface of the tape's active support arm 24 is Being slightly below the plane, the head near the physical edge of the tape 28 The improved contact with the tape and the arcuate shape of the transducer 34 allow for the Loop 28 will be recorded more consistently. Further, the converter 34 and the tape 2 8 is maintained at a relatively low level, extending the life of the tape and head. Violated.   For example, the difference between the reference plane of the transducer 34 and the active support arm 24 of the tape is 0. 025 mm (0. 000984 inches). 0. 025mm gap Is the physical edge dimension of the tape 28. 25 mm (0. 00984 Inn H), it is known that sufficient reading / writing is performed. the above Is linear and parallel to the end face 30 of the transducer drum 32 It corresponds to the tape support surface 44. However, this example shows various end faces and textures. It illustrates the general principles applicable to loop support configurations.   The support arms 22, 24 may be secured to the transducer drum 32 in various ways. However, the support arms 22 and 24 surround the converter drum 32 (see, for example, FIG. 4). It is integrally formed as a part of the part cover 40. The support arms 22 and 24 Each minimizes wear on the tape 28 and minimizes contact between the head and tape at the edge. An improved tape support surface 42, each along the tape feed direction, 44.   The substantially circular end face 30 of the drum 32 is fixed to the tape 28 by the support arm 22. Transmitter drive at a slight angle to penetrate the center rather than the edge of the tape To the system 32. This intrusion causes the central portion of the tape 28 to stretch. Have been banished.   As will be described in more detail below, the end face 30 of the transducer drum 32 has a non-planar shape. There is a case. The end face 30 of the transducer drum 32 is arranged so that the tape is in the immediate vicinity of the read / write It has a shape that supports it. As shown in FIG. 1, the end face 30 is adjacent to the transducer 34. It has a contiguous taper point 46. As a result, the tape 28 is read / written. The taper point 46 on one side of the recess 36 and the support surface 44 on the other side Supported. When the tape supporting portions 46 and 44 approach each other, the head and the tape are moved. The contact with is improved.   In another embodiment shown in FIG. 2, the end face 30 'of the transducer drum 32' is Curved, conical, or supporting tape 28 at a location 48 adjacent to vessel 34 '. It has a spherical shape. Curved, conical, or spherical surfaces can be used with rotary transducers. There is a further advantage in that the drum 32 'reduces the possibility of damaging the tape. Figure 2 Although it shows a roughly uniform curved surface, the asymmetrical curved surface enhances the contact between the head and the tape It will be appreciated. For example, the tape tension is increased through the read / write unit. To increase, end face 30 'can be very close to transducer 34'. You. One embodiment of the conical end face 30 'has a constant radius of curvature at the center of the end face. 3. Crab is large, radius of curvature is small along the edge, approximately 4. 5 inches And has a radius of curvature in the range of 5 inches. FIG. 3 illustrates that the support arms 22 ", 24" are substantially the same length. 1 is another embodiment of the present invention. However, the transducer drum 32 " It is inclined at an angle to it. Thus, the isolation region 26 "is disconnected from the transducer path. It is formed so as to approach the touching portion 38 ". The tape 28 penetrates along the writing portion 36 ". The tapered or curved end surface 30 , 30 'can contact the inclined transducer drum structure 32 "shown in FIG. Will be done. As described above, the isolation regions 26, 26 ', 26 " The head can penetrate the center of the tape and change the vertical tension across the tape. At as small an angle as possible, the tape 28 comes into contact with the transducer drum. head Head and tape contact do not coincide, especially at the edges Maybe. The curved tape support provides vertical tension along the edge of the tape. increase. A more complementary support is better for the end face 30 of the transducer drum. , 30 ', 30 "in tape or preformed tape be able to.   FIG. 19 increases the penetration of the head into the tape in the direction of the center (not shown) of the tape. Another tape support arm 36 with a concave, tape support surface 362 0 is a side view. Relative penetration of transducer drum 366 near the edge of the tape The recorded arc extends near the edge of the tape be able to. Contact between head and tape at tape edge by using alternately As the pressure decreases, the output signal decreases and the error rate increases. However While moving away from the edge of the tape, the head enters the tape more effectively As a result, a higher contact pressure and better electromagnetic conversion can be obtained. In this way, The length of the arc that can be used near the edge of the tape is also increased, but the concave The loop support 362 provides efficient recording through most of the arc.   FIG. 20 shows another tape support arm 3 with a convex tape support surface 352. It is a side view of 50. The tape support surface 352 is at the end of the transducer drum 356 Complementary to surface 354 or to circular edge 358 of transducer drum 356 It has a curved shape that bends a tape (not shown) in an engaging manner. Convex support 3 52 is a central portion of the tape further away from the end surface 354 of the drum 356 (not shown). ), Which bends the edge of the tape in the direction of the end face 354. This The tape support 352 having such a contour is formed by the non-planar end face disclosed in FIGS. It has been found to be particularly effective when combined with structures 20, 20 ". Was.   Convex, concave, or linear tape support surface on a single transducer assembly Can be combined. For example, a convex tape support is used for the read / write unit. Used adjacently, a linear tape support is used on the opposite side of the transducer drum You.   FIG. 16 is a perspective view of the bow-shaped scanning tape driving device 300 as an example. Fret The arm 302 stores a double-reel type cartridge 304 of a belt drive type. I have. The tape driving device 300 stores the cartridge 304 and Open the tape cover 312 to expose it, and record and replay the tape 308. It includes a conventional cartridge loading mechanism 306 for raw positioning. tape· When a force is applied to the capstan roller 310, the tape 308 is driven longitudinally. Move. The cartridge is a tape guide attached to the cartridge 304. (Not shown) (see below for FIGS. 9, 10 and 15) . The tape 308 is attached to the end face of the rotating head transducer assembly 322 (see, for example, FIG. 4). The tape from left to right through read / write area 314, which contacts the transducer on Moving.   The force to advance the tape in the longitudinal direction is applied to the capstan via the transmission assembly 316. Roller 318 is applied. By way of example, the transfer assembly 316 may read / write To advance tape 308 through region 314, tape capstan 31 It has a capstan roller 318 that contacts the zero. Various transmission devices Suitable for this purpose, what is illustrated above does not limit the scope of the invention never.   As the tape 308 advances through the read / write area 314, the data is Recorded (written) on the tape by the head transducer assembly 322 or Read from the loop (playback).
