Abstract:
A tape storage device having information for converting longitudinal physical positions (102) written in a medium to logical positions used by a tape drive. The conversion information, an offset and an optional maximum physical position value, are stored in one or more locations (106, 108) in the tape storage device. Methods of operating the tape drive are disclosed to determine and store the conversion information in the tape storage device. Another method of operation enables the tape drive to read the conversion information and convert the physical positions (102) to logical positions. The method works for both center loading and end loading medium. Possible numeric rollover of the physical positions is detected by one of several methods including the step values between adjacent physical positions, comparing the logical positions with an upper and lower boundary, and generating a lookup table where the rollover is represented by a wraparound between the top and bottom of the table.
Abstract:
An apparatus is provided with a thin film magnetic head (20) with eight write units (21-28) positioned adjacent to each other in a transversal direction (y) to write data in parallel tracks on a magnetic tape (10). Switching means (70) are provided with a switch (SW) to switch from a normal mode to a combination mode. In the normal mode the switch (SW) is in a first position (D1) and the switching means (70) couple a first data signal (S1) to a first write unit (21), a second data signal (S2) to a second write unit (22) etc., so that in the normal mode eight tracks (T21-T28) are written on the tape (10), resulting in a first track density. In the combination mode the switch (SW) is in a second position (D2) and the switching means (70) couple the first data signal (S1) to the first and second write units (21 and 22), the second data signal (S2) to the third and fourth write unit (23 and 24), etc. Hence, in the combination mode, four tracks (T1-T4) are written on the tape (10), resulting in a second track density which is half the first track density. This second track density corresponds to the density of the write units of a magnetic head (2) of an apparatus (not shown) of an older generation.
Abstract:
A recording format comprising, in order to improve the adjustement efficiency of a high density recording/reproducing device by automatic adjustement and to realize excellent compatible reproducing characteristics despite the characteristics variation of the magnetic head, change of characteristics due to wear and characteristics variation of the recording medium, two recording areas of the single repetitive data of a reference wavelength for the adjustment of a reproducing amplifier and a short wavelength for the adjustment of a reproducing equalizer, a recording area of adjustment data for the error detection and the precise adjustment of the reproducing equalizer, one or more no-data areas for the recording system adjustment, identification data which indicate that the medium is for the automatic adjustment and indicate the types of the areas depending on the kind and necessity, and, if necessary, time codes; a recording device which recordes the recording format in recording medium; and an automatic adjustment device which performs automatic adjustment by using the data of the recording format on the reference recording medium.
Abstract:
The meta-data, as defined in SMPTE 298M and 335M buried in a video voice material signal to be recorded in a magnetic tape (30), are extracted, and either these extracted meta-data or the meta-data generated from the information other than the material signal are written in a non-contact type memory tag (37). As a result, without reproducing the material recorded actually in the recording media, the meta-data on the material recorded in the recording media can be obtained to help a retrieval or a confirmation.
Abstract:
A recording and/or reproducing apparatus (1) adapted to receive a record carrier (4) advantageously includes a transponder communication device (35) having a planiform station transmission coil (37) for the contactless communication with a record record-carrier transmission coil (50) combined with the record carrier (4), and includes holding means (51) for holding the station transmission coil (37) which extend away from the station transmission coil (37) into the space which is remote from the record-carrier transmission coil (50).
Abstract:
A hand-held portable reader (200) and labeling device for interrogating data storage cartridges of the type containing an in-built memory chip having information stored describing details of data contained on the data storage medium is disclosed. The reader-labeling device comprises a processor, random access memory, printer (203), display (205), keypad (206), operating system, transponder, receiver and battery power supply. By scrolling a menu display, key parameters describing a data cartridge can be accessed quickly and efficiently without the need to access the data storage medium itself. A cartridge media specific label may be rapidly printed for attachment to a data storage cartridge.
Abstract:
A directory of programs recorded on a cassette tape is provided to facilitate recording and reviewing of the programs and allocating and deallocating of space on the tape. The directory is either stored on the cassette tape itself or on an external memory. Designs of the various components for providing and maintaining the directory are also disclosed.
