Abstract
PURPOSE: To shorten the access time by using only one detector area by detecting magnetic-bubble advance directions of both read lines on the odd side and even side by leading both the lines into one near a boundary area.
CONSTITUTION: In a magnetic bubble memory element on the odd/even system, magnetic bubbles flowing through odd-side 101 write line 81 and read line 51 are opposite in advance direction. As a result, data on odd side 101 and those on even side 102 both advance toward odd/even boundary area 103, enter detector area 6 after curving at right angles, and are detected getting together. The number of bits from initial data position 301 on odd side 101 to detector 64 differs by one from that from initial data position 302 on the even 102 side to detector 64 and consequently a series of data can be obtained, so that the mean access time can be shortened.
