Abstract

PURPOSE: To accurately detect data write positions by reading out the address information of address tracks thereby retrieving the write or read positions.
CONSTITUTION: A tape is set at the beginning of the address starting writing, e.g., 9, and the final writable address, i.e., threshold address, e.g., 20, is set in a register 32. While the address tracks are being read, data are written under comparison of the current address 31 and thershold address 32 in a comparator 24. Upon finishing of writing, the write start and finish addresses are stored as effective data into a main memory device 28. If the current address reaches the threshold address during progressing of writing, the writing is immediately stopped and the data are rewritten from the beginning freshly in another place.
