摘要： A digital recording and reproducing method and system by which a desired control code can be recorded onto and reproduced from an analog record tape to improve the operability in reproduction of such analog record tape. A fixed head unit is used which has a first track face on which an analog head is provided and a second track face on which a plurality of digital heads are provided. Upon analog reproduction or recording onto or from one of a pair of analog tracks of a tape by means of the analog head, a desired control code is digitally recorded onto a non-recorded gap portion of the other analog track using a particular one of the digital heads. Then, upon analog reproduction by the analog head, the digitally recorded control code is read out from the tape using the digital heads.

摘要： In a magnetic tape apparatus (1) with a magnetic head (28) which can be turned essentially through 180.degree., the magnetic head is attached on a head support (37), which is rotatably mounted by means of a bearing device (46) on the apparatus and has a channel (69) leading to the magnetic head (28), through which channel unshielded sections of leads (105, 106, 108) of a cable (107) shielded outside the channel (69) with a shield (109) are led to the magnetic head (28). In this case, the head support (37) consists of electrically conductive plastic and is electrically connected to a reference potential terminal (111) on the apparatus, as a result of which the in fact unshielded sections of the leads (105, 106, 108) within the channel (69) of the head support (37) are also shielded against interfering electromagnetic radiations.

摘要： A computer-implemented method for determining a damaged area of a magnetic tape loaded in a tape drive, according to one embodiment, includes: determining a first error location on a magnetic tape where a first error occurred in response to experiencing the first error. Moreover, the method includes determining one or more areas on the magnetic tape to be examined. The one or more areas are determined using a predetermined algorithm which incorporates the first error location. Independent of a read and/or write operation, relative motion is induced between a tape head and the magnetic tape such that the tape head is positioned adjacent to each of the respective one or more areas in turn. Furthermore, each of the one or more areas having a respective number of measured servo errors which exceeds a threshold value is identified as a damaged area of the magnetic tape.

摘要： In one general embodiment, an apparatus includes a first outer module having an array of writers, a second outer module having an array of writers, an inner module positioned between the outer modules, and a first actuator for shifting the first outer module. The shifting is relative to the inner module, in a cross-track direction by about one half of a center-to-center pitch of the writers of the first outer module. The inner module has an array of readers.

摘要： The invention provides a tape drive comprising a head mounted on a turntable. The turntable rotates to allow the head to access first and second sides of a data storage tape. Techniques for accessing the first and second sides may include rotating the turntable to position the head in first and second positions. In addition, the techniques may further include raising and lowering the turntable relative to the data storage tape in order to facilitate access to both sides of the data storage tape without requiring the data storage tape to be unspooled and re-spooled.

摘要： A first data group in an access sequence is selected. A distance from a current position of the tape medium is set to be a logical distance value, determined by a calculation function, that is substituted for the physical distance value for the data groups that are located in the specified regions as compared with other data groups located in the alternative specified regions. A second data group in the access sequence is selected. The logical distance value is then determined by multiplying a coefficient based on a physical positioning of each of the data groups in the tape medium, and a percentage of those of the plurality of data groups that have already been selected as the first data group and the second data group.

摘要： A first data group in an access sequence is selected based on which data group in the data groups has a beginning closest to a current position of the tape medium. Those data groups located in specified regions of the tape medium are separated from other data groups located in alternative specified regions of the tape medium. The distance from the current position of the tape medium is set to be a logical distance value, determined by a calculation function, that is substituted for the physical distance value for the data groups that are located in the specified regions as compared with other data groups located in the alternative specified regions. A second data group in the access sequence is selected based on which remaining data group in the data groups has a beginning closest to an end of the first data group in the access sequence.
