Picture Rotation on Magnetic Bubble Matrix Available to Purchase

Two possibilities are conceived in the application of the magnetic bubbles. One of them is for mass memories to replace magnetic drums or magnetic disks. Whereas another is for some novel functional devices utilized in such field as picture information handling and others. By using 52um thick $TmFeO3$ orthoferrite platelet and 1.2um thick permalloy chips, we realized some functional shift matrixes having the capabilities of shifting the bubbles in two dimensional directions. In the reference 1, we had pointed out that this functional shift matrix is well suited to realize an array logic function, and had described the concepts of the picture rotation on this functional matrix. We have developed an $9 × 9$ bits experimental model of picture rotation device and have experimentally verified the function of the picture rotation.
