Abstract
A magnetic bubble memory device comprising a cassette holder provided in a main bubble memory apparatus and a magnetic bubble memory cassette which is inserted into the holder so as to be electrically connected with a bubble actuating circuit provided in the main bubble memory apparatus. The device further comprises a detector means for detecting the operation of ejecting the cassette from the holder. The detector means transmits a signal for stopping the bubble motion in advance of the disconnection of the cassette from the bubble actuating circuit.

A magnetic bubble memory device comprising:
- a main bubble memory apparatus having a bubble actuating circuit and a holder;
- a magnetic bubble memory cassette which is inserted into said holder so as to be electrically connected with said bubble actuating circuit provided in said main apparatus;
- detector means for detecting the operation of disconnecting said magnetic bubble memory cassette from said holder, said detector means including means for transmitting a signal for stopping the bubble motion caused by said bubble actuating circuit in advance of the disconnection of said magnetic bubble memory cassette from said bubble actuating circuit.
A magnetic bubble memory device capable of receiving a cassette, comprising:
- a bubble actuating circuit;
- a cassette holder having an inlet for receiving the cassette, said cassette holder electrically connecting said bubble actuating circuit and the cassette;
- means for ejecting said cassette from said cassette holder;
- and
- means for detecting the actuation of said ejecting means and for generating a disable signal to disable said bubble actuating circuit, thereby stopping bubble motion in said cassette prior to the electrical disconnection of said cassette from said bubble actuating circuit.
