Title: Magnetic bubble memory element
Inventor: YANAI MASAHIRO
IPC: G11C11/14
Filed: 1983-11-21
Abstract: PURPOSE:To obtain excellent transfer characteristics without generation of a margin loss at start and stop actions by making a transfer period, which is connected to the moving-out side of a magnetic bubble of a reverse 180 deg. corner pattern, more than a 1.3-fold basic tansfer pattern period of a minor loop. CONSTITUTION:A magnetic bubble memory element has a reverse 180 deg. corner pattern on a minor loop. A period of a transfer pattern adjoining to the moving- out side of the bubble is made more than 1.3 times a basic transfer pattern of a minor loop. The figure shows the relationship of a start/stop margin loss L and a period lambda' of a basic transfer pattern 5d'. As shown in the figure, along with an increase the period lambda' the margin loss L decrease, and in case of lambda'>=1.3lambda, the margin loss L becomes almot zero. The upper limit of a bias magnetic field in start/stop actions is limited by a transfer action. When the period lambda' is made larger so as to magnify a pattern volume, a magnetic bubble can be stably stopped on an A part of the basic transfer pattern 5d'; therefore a margin loss be eliminated.
