METHOD OF OUTPUTTING THE NUMBER OF BLOCK

摘要

The method reads charge data stored in a disk temporarily by blocks. The charge data is handled by man-machine communication method. The method includes the steps: (A) reading R/W sector address from disk according to charge data request signal, and reading the sector designatd by the R/W sector address and sotring on a temporary buffer; (B) checking that the read sector adress is higher than write sector address; (C) subtracting the read sector address from the write sector address to find charge data to be transmitted to a magnetic tape (MT) and storing on a temporary buffer when the write sector address is higher than the read sector address; (D) comparing the size of read and write point; (E) subtracting the read point from the write point and storing on a block storing buffer when the write point is larger than the read point, and so on.
