Abstract: A system and method for implementing a boot recovery on a data processing system. According to an embodiment of the present invention, at least one processor compares contents of a first read-only memory (ROM) image and a second ROM image outputted from a memory. The first ROM image is initially selected to boot a data processing system utilizing a first basic input output system (BIOS) program. In response to determining that contents of the first ROM image and the second ROM image are different, the second ROM image is selected. The data processing system boots utilizing the second BIOS program stored by the second ROM image.

Abstract: The present invention is a system and method for generating a barcode with a human readable interpretation (HRI), herein the barcode includes an application identifier. The characters are input as an input data set that is equivalent to the complete (HRI) with a special character immediately after the application identifier. Generating a barcode encoding data set for encoding the barcode is based on the input data set. Generating the barcode encoding data set includes interpreting the special character as a field separator between the application identifier and a data portion. Generating a data set for the human readable interpretation is based on the input data set and includes converting the special character to a symbol. Generating the barcode with the human readable interpretation includes combining the barcode encoding data set and the data set for the human readable interpretation.

Abstract: A printer for printing to label paper and other types of continuous paper minimizes wasteful consumption of continuous paper and enables operating in a self-printing mode conforming to the specifications of the continuous paper currently in use. The printer prints to roll paper including label paper having a plurality of labels affixed to a continuous web backer with a gap between the labels. A paper transportation control unit controls the transportation mechanism for conveying the roll paper along a transportation path. A printing control unit controls a printing mechanism including a print head disposed to the transportation path. A sensor disposed on the upstream side in the transportation direction from the print head detects paper information about the roll paper. A print data generating unit generates the self-printing data based on information stored in the printer.

Abstract: A storage device in which file data is divided into multiple blocks for storage on a recording medium. The storage device includes an additional data storing section for storing additional data to be recorded on the recording medium in association with the data to be written, a position determining section for determining recording positions on the recording medium where the blocks should be respectively written, based on the additional data, and a block writing section for writing the respective blocks on the recording positions on the recording medium determined by the recording position determining section. The additional data thus defines a gap length between blocks of recorded data. During a read operation, if the gap length does not comport with the additional data, then an error is assumed.

Abstract: A storage apparatus for sequentially writing a plurality of blocks of data generated by dividing data on a data recording medium, the storage apparatus including: a sequential writing unit for sequentially associating and writing each of the plurality of blocks with validity information indicating whether or not data contained in the block is valid, on the data recording medium; an error detecting unit for detecting that writing of a single block causes the validity information of the single block to be written in an error area that generates a write error on the data recording medium; a write-area changing unit for changing a write-area in which an additional block is written to cause the additional block written before the single block, excluding the validity information of the additional block, to be written in the error area and the validity information of the additional information to be written in an area other than the error area; and an error circumventing unit for writing the single block in a write-

Abstract: A printer with a peeler mechanism 1 for peeling labels from a web, the printer having a movable web pressure roller 24 which may be moved from a web pressure position 24A in which pressure is applied to a platen roller 20 to a retracted position 24B in which pressure is not applied. The printer also has a photosensor 21 and photoreceptor having an emitter/receptor surface 21a for detecting the presence and absence of labels peeled from the web. A window 22b in the label guide surface 22a becomes covered to shield the photosensor output for defining a no-label detection stateWhether the peeler mechanism is set to operate in the label peeling mode or is set to a retracted position defining a non-peeling continuous label dispensing mode of operation can be determined based on the output of the label detection photosensor 21, and the label dispensing mode can be set to the label peeling mode or continuous label dispensing mode based on this determination.

Abstract: A storage device in which file data is divided into multiple blocks for storage on a recording medium. The storage device includes an additional data storing section for storing additional data to be recorded on the recording medium in association with the data to be written, a position determining section for determining recording positions on the recording medium where the blocks should be respectively written, based on the additional data, and a block writing section for writing the respective blocks on the recording positions on the recording medium determined by the recording position determining section. The additional data thus defines a gap length between blocks of recorded data. During a read operation, if the gap length does not comport with the additional data, then an error is assumed.

Abstract: A method and system for rewriting data on a tape when an error occurs during an initial write operation. When the initial write error occurs, the data is rewritten at a location that is a pre-defined block gap distance from the last valid write location on the tape. By measuring the length of the pre-defined block gap distance, the cause or causes of the write error or errors are known. Thus, the pre-defined block gap not only ensures that the data is not re-written in a no-write zone of the tape, due to the zone known to be error prone, but a historical record of past write errors is logged based on the length of the block gaps.

Abstract: When a testing system is connected to a debug port of a tape drive unit or a SCSI bus, a self-checking test for a fabricating process is executed. When the testing system is not connected, the self-checking test for normal operation is executed. And in a test of a single card, a motor test and an MR head resistance test, which are tests of a mechanical structure portion, are omitted. In addition, in a box assembling process, the test contents are suppressed to a minimum prior to adjustments to the, tape head. Furthermore, in a test program, the status of a flag or an indication corresponding to a test executed in a next step is changed.
