摘要： A tape driving apparatus and a recording medium, capable of detecting a target running amount during High Speed Search. Wherein upon a search command, a system controller sets a target position based on a specified position specified by this search command. Then, the system controller calculates the target running amount from the current position to the target position based on a spanned distance and calculates the target count value as the running amount corresponding to the calculated distance. Then, the system controller runs the magnetic tape while counting the reel FG pulses and shifts to High Speed Search. Starting High Speed Search, the system controller judges whether or not the count value of the reel FG pulses has reached the target count value. When it judges that the count value has not reached the target count value, it considers that the target position has not been reached yet and continues High Speed Search. When, it judges that the count value has reached the target count value, it shifts to Normal Search. After shifting to Normal Search, it judges whether the specified position has been reached or not based on information read out of the magnetic tape and when it judges that the specified position has not being reached yet, it continues Normal Search. When it judges that the specified position has been reached, it ends the search.

摘要： A tape cassette and a tape streamer drive for driving the tape cassette are provided. MAFN data and VMAFN data are defined so as to indicate the maximum frame number of all frames formed in a partition and the maximum frame number of frames in a valid area in the partition, respectively. The MAFN data and the VMAFN data are stored in a MIC disposed in the tape cassette. The size of an available recording area remaining in the partition is calculated from the MAFN data and the VMAFN data. Thus, a powerful technique is achieved for managing the tape cassette used in a data storage application.

摘要： A programmable integrated circuit has multi-layer wiring with openings over fuses, and a fabrication method forms the openings for each fuse, to avoid damage due to the blowing off of the fuses. The forming of the openings is performed by etching each insulating layer on the fuses after it is formed over the pre-formed wiring-layers. This results in shorter etching time as compared to the prior art etching method where the openings are etched in all the layers for the whole depth in one process step. Because of the shorter time necessary for each etching, overetching and side-etching are reduced, thus providing the openings with more accurately determined dimensions, which provides higher yield for manufacturing the device. The contact holes and the windows for the bonding pads in each insulating layer are etched in the same fabrication step for forming the openings for the fuses in the same insulating layer. This requires no additional fabrication processes for the IC and results in no increase of the fabrication time and cost.
