    Abstract: Even if a read error of data in a tape management area takes place due to a scratch on the tape, the management area data can be securely restored by the retry process.Assume that the initial value of the physical ID is equivalent to 4000ID that is the distance measured from the PBOT. After the normal write process for the VSIT is performed, the initial value of the physical ID becomes -1600ID (see FIG. 19A). After the first write retry process has been performed, the initial value of the physical ID becomes -1700ID (see FIG. 19B). After the first write retry process has been performed, the initial value of the physical ID becomes -1800ID (see FIG. 19C). Thus, whenever the retry process is performed, the initial value of the physical ID is decreased for 100ID. On the other hand, the VSIT is written from 0ID. In the retry process for the VSIT, the physical ID of the start position is not changed. However, the real write position (namely, the distance measured from the start position) is changed. Thus, even if the write data of the VSIT has an error due to for example a scratch on the tape, the write error of the VSIT can be recovered by the retry process.

    Abstract: An automatic scan tracking, helical tape type of data recorder is disclosed herein along with its method of operation. Data is written onto magnetic recording tape along with data retrieval information by means of a rotating scanner assembly forming part of the recorder as the recording tape moves at a given recording speed in cooperative engagement with the scanner assembly. Data is normally retrieved from the recording tape along with the data retrieval information by means of the rotating scanner assembly as the recording tape moves longitudinally at the same given recording speed. In operation, the rotating scanner assembly of the recorder retrieves data and data retrieval information from a segment of the recording tape while the latter is not moving, that is, during a period when the tape is stationary for enabling adjustment of the read head position relative to the track depending on the evaluation of the data resulting from the stationary tape read. Provision is also made for causing the rotating scanner to retrieve data retrieval information from a segment of the recording tape while the latter is accelerating from a still state to its given recording state, with subsequent evaluation of the data and adjustment based on the results.

    Abstract: An 8-9 converting circuit converts 8-bit data into 9-bit parallel data. A sync pattern/ID pattern adding circuit adds sync patterns and ID patterns to the 9-bit parallel data and sets values for the ID patterns according to a predetermined correlation between a position of an mth ID pattern and a distance from an nth sync pattern to an mth sync pattern. A parallel/serial converting circuit converts the parallel data into serial data and the resultant serial data is recorded on a tape. Data reproduced from a tape is supplied to a serial/parallel converting circuit which converts the serial data into parallel data. A sync pattern/ID pattern extracting circuit extracts sync patterns and ID patterns from the parallel data, extracting as valid an mth sync pattern whose corresponding mth ID pattern has a value set in accordance with the predetermined correlation. An 8-9 inverse converting circuit converts the parallel data into 8-bit data corresponding to the extracted sync patterns and ID patterns.

    Abstract: The control software and hardware in the tape drive control unit creates and manages a header segment at the beginning of the magnetic tape. This header is interposed between a leader portion of the magnetic tape on the 3480-type cartridge and the remainder of the magnetic tape contained therein. This header segment contains two sections, a first of which is a data record directory that is used by the control unit to denote the location of each data record written on to the magnetic tape as well as administrative information associated with the data record. The second section of the header is an administrative information section that contains data relating to the magnetic tape itself. The administrative information includes the identification of the tape volume, the tape drive, write protect status of the magnetic tape, identification of the media, error record log and other information that enables the user, the host processor and the tape drive control unit to manage the data records written onto the magnetic tape without reference to any other sources of administrative data. In addition, the header itself can be self protected by computing an error correction code across the data contained within the header to enable the control unit to identify whether the header integrity has been compromised.
