PURPOSE:To allow reading or writing of the required data in a short time by storing the data with a small size in a minor loop which is near a bubble generator. CONSTITUTION:Data with a small size are stored in a subminor loop 14 which is located near a bubble generator 11. Storing is executed through a replicate/transfer gate controlled by a controller which generates a timing pulse in accordance with a condition instructor indicating no existence of remained data in a major line 13 which corresponds to a comparator and a loop 14' indicating whether or not the output of a physical and logical address changing means which changes at every driving period of the rotational field is fit to the requirement, and the small block information is packed and stored in a line 14'. For the reading by a magnetic bubble detector 12 of the storage information, the unnecessary minor loop 14 does not participate the operation, and the detector can read and write only the required data in a short time in the same way. |
