PURPOSE:To enable the writing and reading for devices of different capacities and constitutions, by inserting a cassette type magnetic bubble memory added with an index loop in which the career of an element is recorded to a magnetic bubble memory element into a main body device in an attachable and detachable way. CONSTITUTION:An index part B including an index loop 23, a writing swap gate 24, a reading replicate gate 25, a reading line 26 and a detector 27 is added to a normal major/minor constituting part A. The career of each element is stored previously into the loop 23. Such cassette type magnetic bubble memories 28-31 are loaded into a main body. Thus a controller 34 reads and studies the information stored into the loop 23 of a cassette to perform the writing and reading. In such way the writing and reading is possible for plural bubble memory devices of different capacities and constitutions. |
