PURPOSE:To erase the undesired magnetic bubble in a simple way without using a current pulse, by using a margin circuit using the crystalline magnetic anisotropy. CONSTITUTION:A reading major line 27, writing major line 28, etc. where the erasion is desired for the undesired magnetic bubbles contain a margin circuit comprising a pat track (b) using the crystalline magnetic anisotropy, a super- track (s) having a large margin, etc. As a result, an undesired magnetic bubble 29 reaching a gap 30, etc. is assuredly led into a guard rail 26 formed with a good track (g). In such way, the undesired bubbles can be erased neither using a current pulse nor complicating the constitution of a power supply circuit, etc. |
