PURPOSE:To prevent the generation of spark discharge due to the electrification of a cassette case, by using conductor to form a contact part between a cassette type magnetic bubble memory of a holder device and the cassette case. CONSTITUTION:A holder case 31, a rear cover 32, a spring 41, etc. of a holder device 48 are made of floating metallic materials given from the frame and signal grounds of the device 48. The device 48 has a contact with the case part of a molded insulator of a cassette type magnetic bubble memory 51. Thus the electrostatic charge of the case of the memory 51 escapes into a metal and then quickly leaks into the air to prevent the generation of spark discharge. This prevents the breakdown of a magnetic bubble which is due to the noises produced by the spark discharge. |
