Abstract: An apparatus for positioning a magnetic tape head (3) transversely relative to a length of magnetic tape in a magnetic tape recorder along a shaft. The shaft (6) vertical axis may be slightly tilted to compensate for manufacturing tolerances and achieve the necessary alignment of the magnetic tape head to the magnetic tape (3) path. To accomplish this, one end of the shaft (6) is supported in a washer bracket (12) for connecting that end of the shaft to the tape drive frame (1). The washer bracket (12) is pre-loaded axially of the shaft (6), such that a directing force applied to that end of the shaft permits the washer bracket to slide in a direction transverse to the axial direction of the shaft on the frame. Otherwise, the washer bracket (12) frictionally abuts the frame (1) and holds that end of the shaft (6) in fixed position on the frame (1).

Abstract: The invention pertains to developments for manipulating and referencing a magnetic tape cassette in a magnetic tape device involving loading, read/write and tape drive operation, and unloading. To load and unload the tape cassette, a tape drive bridge on which the magnetic head is mounted is disposed in a standby position out of the way of the path of movement of the tape cassette into and out of the recorder housing. A gripper disposed for longitudinal movement on a gear rack in the recorder housing, is arranged to bite the cassette to automatically carry the cassette inwardly to its fully loaded position and then again move the cassette outwardly to its unloaded position. A lever arm arrangement is provided to appropriately open the dust cover door on the tape cassette, to expose the cassette tape for operational engagement by the magnetic head, as the tape cassette approaches its fully loaded position within the recorder housing. The gear rack serves to activate this lever arm for opening the dust cover. The tape cassette is preferably loaded endwise into the recorder housing, and when the cassette has been fully loaded in the recorder housing, the tape drive bridge carrying the magnetic head is rotated in all three axes from its standby position to its running position. In its running position, the tape drive bridge locks the tape cassette to it, by gripping the cassette at three reference areas on the bridge. A manual eject mechanism utilizes an exposed button on the recorder housing which is manipulated by the operator to causing unloading of a stranded tape cassette, should the electrical system not work.

Abstract: A method and apparatus for positioning a magnetic servo head relative to a servo track on a traveling magnetic tape both make use of the observation that a given tape in a given tape drive unit exhibits transverse tape movements during operation which constitute a "signature" waveform for the coupled tape cartridge and drive unit. In the method and apparatus, the transverse movements of a traveling tape in a drive unit are monitored to obtain the aforementioned waveform which is characteristic of the transverse movements for that tape, and the waveform is stored. The positioning of the servo head is controlled relative to a servo track on the tape using a control signal generated according to any known track seek algorithm. The stored waveform is recalled and is superimposed on the control signal, thereby significantly increasing the accuracy of the positioning of the servo head, which in turn increases the accuracy of positioning of the write/read head.

Abstract: A method and apparatus for reading data contained in blocks arranged in a number of tracks on a storage medium, wherein movement of the storage medium causes the tracks to deviate from a nominal path, are disclosed. In the method and apparatus, a set of multiple read elements (R o ,R c ,R u ) is disposed relative to the storage medium so that each of the read elements covers at least a portion of the expected area in which a track to be read will be found, given movement of the storage medium. Each of the read elements has a read channel uniquely associated therewith, and all of the read elements are used simultaneously to read the data blocks. The read channels are monitored, and a first arriving, correctly read block is selected from among the channels, the selected block being the next block in a sequence, following a previously selected block. The data blocks are then stored at memory locations correlated to their position in the sequence on the storage medium.

Abstract: A method and system detect and correct for errors on a tape resulting from, for example, debris on the tape. Location of the tape is continuously monitored, and when an error is detected during a data transfer operation, the tape is moved and re-positioned to rewrite a data block where the error was detected. If the error is not corrected, a minimum threshold requirement is decreased so the system detects the data block as corrected thereby avoiding system hang-ups or the like.

Abstract: A magnetic head which contacts the magnetic tape (11) comprises a ferromagnetic body (12). A recess (26) is provided in this ferromagnetic body (12). A ferromagnetic core (9) has pole tips (9a,9b) which are located in the recess and which are arranged for contact with the magnetic tape. A non-magnetic material (18,20,21,22) is arranged along each side of the magnetic core pole tips in the recess. Relative hardnesses of the ferromagnetic body, ferromagnetic core pole tips, and non-magnetic material are chosen so that as the tape (11) wears away on contact surfaces of the magnetic core pole tips, non-magnetic material, and ferromagnetic body, the core pole tips (9a,9b) protrude relative to adjacent portions of the ferromagnetic body and the non-magnetic material so that the tape rides on the protruding pole tips of the core. A radius of curvature at the contact surface of the magnetic core pole tips prior to wearing of the pole tips is chosen such that it is smaller than a natural radius of bending of the tape.

Abstract: 5 n7 A device for positioning a magnetic head to an operative position relative to a selected track of a multi-track magnetic tape in a magnetic tape write/read device. A magnetic head is disposed at one end of a magnetic head carrier while the opposite end of the head carrier is axially movable along a shaft fixed to the tape recorder housing frame. An inchworm-type servo system is provided which has two clamping devices arranged stacked axially along the shaft and a positioning device connected between the two clamping devices which can be altered in length to move the clamping devices toward or away from each other. By alternatingly clamping the two clamping devices to the shaft and altering the distance between the two clamping devices in coordination, the servo system can crawl up and down the shaft to position the magnetic head. In another mode of operation, the clamp which mounts the head carrier is left unclamped with respect to the shaft, the opposite clamping device is clamped with respect to the shaft, and the extending device is allowed to expand or contract over its operable range to minutely position the head with respect to the tape. In the preferred embodiment, the clamping devices and the extending devices are piezoelectric elements which receive a voltage potential to correspondingly expand or contract. By contracting the clamping devices are actuated to clamp tightly to the shaft to prevent axial movement.
