Abstract
PURPOSE: To retrieve the whole record of 1 track by one start, by providing the comparison information store buffer in each sector unit in the computer system, continuously reading a record on the disk, and comparing it with a record in the comparison information buffer.
CONSTITUTION: The intrinsic name of a record to be compared is set to the buffer 4, at the same time its record length is set to the register 7, and the number of blocking sectors is set to the register 8. Subsequently, when the disk apparatus 6 is started by a program, the scanning circuit 5 transmits a data continuously by a sector each to the information comparator 3 from the disk. The circuit 3 compares the contents which have been read out by the circuit 5, with the contents of the buffer 4, stops scanning if the record intrinsic names which are set from the n-th byte from the head are matched, displayes the character position in the sector position sector in that case, in the disk address displaying circuit 2, and if they are not matched, the comparison is repeated from the position where the record length shown in the register 7 has been added.
