PURPOSE:To prevent a shutter from getting out of a store case by extending the shutter groove of the store case up to the edge of the case and closing the groove end part with a stopper member after putting the shutter into the groove. CONSTITUTION:A groove 33 is formed to a store case 1 for magnetic recording medium which consists of upper and lower wafers 31 and 32, and this groove 33 is extended up to the edge of the case 1. A pawl 52 of a shutter 51 for aperture opposite to a head is put into the groove 33 from the edge part of the case 1. Then the shutter 51 is shifted, and the end part of the groove 33 is closed by a clamper 55. In such a constitution, the shutter 51 is prevented from getting out of the groove 33. |
