Abstract

PURPOSE: To shorten the whole of the processing time, by using the boundary mark of the data block or the data file to raise the tape running speed between data blocks or data files.
CONSTITUTION: For the tape running between data files, the tape running speed of C1 is increased only by the oblique-line part as shown in C1WC3. TM is detected by the write-in head previously, and the tape is decelerated to prescribed read speed V0 before the read head reaches TM. Tape running speed V1 of C1 is decelerated to speed V0 by TM detection of the write head of C2, and the tape is stopped by TM detection of the read head of C3. The tape is accelerated to speed V2 between data blocks as shown in C1, and the tape is decelerated to speed V0 by the rise of the data block of the write head of C2, and data is read by the read head of C3, and the tape is stopped at the fall.
