Title: Method for protecting writing of information recording medium
Inventor: SAITO WATARU
IPC: G11B19/04
Filed: 1994-09-28
Abstract: PURPOSE: To enable written data to be protected and recording medium to be managed by protecting the data of a storage medium with a secure write inhibit mechanism which is not easily returnable to a write-enable state after the mechanism is set in a write-inhibit state in selection of a user or vender. CONSTITUTION: A tab 1 for laterally sliding in order to open and close the write-inhibit hole of a floppy disk has a spring characteristic at its front end and has a projection for fixing the write-enable and write-inhibit positions. A holder 2 for holding this tab 1 has two kinds of projections for fixing the write-enable and write-inhibit positions on the inner side. The hole 3 guides the slide of the tab 1. The write-enable state is attained when the tab 1 closes the write-inhibit hole 4. The write-inhibit state is attained when the write-inhibit hole 4 is opened by sliding the tab 1. The state 5 in Fig. (b) is the write-enable state. The state 6 is returnable to the state 5 and movable to the state 7 as well by running on the projection from the state 5. The state 7 is the state not returnable to the state 6 by running on the projection from the state 6.
