PURPOSE:To synchronize addresses at re-application time of a power supply in a short time, by providing a plurality of exclusive minor loops storing index information and reading the combination of the information. CONSTITUTION:In a lot of minor loops, such as (m) pieces of minor loops 1a, 2a... are used exclusively for index loops and the information are combined together, allowing to set address information in the combination of (2<m>-1) pieces. In reading the address information, without locating bubble stop position to a prescribed location at power failure, the addresses can mediately be synchronized at the re-application of power supply, allowing synchronize addresses at the power supply re-application in a short time. |
