Abstract
A data protection method is used for protecting data recorded on a removable storage medium, such as an optical magnetic disk. The method includes the steps of authorizing to read and access a part of a directory area on a storage medium without specifying a password given to the removable storage medium. When accessing the removable storage medium, a user is required to input a password, the inputted password is compared with a predetermined password, and if not coincident, access is inhibited, and further, if coincident, it is permitted to access only one part of an area of the removable storage medium.
