本发明提供了一种卡式记录媒体，以简化存取授权的设置和更改工作，从而可靠执行安全系统的管理和操作。包括用来存放数据的存储单元以及存取控制单元。存取控制单元包括一个存取主体识别信息产生单元，它产生识别存取主体的存取主体识别信息、一个存取授权信息读入单元，它读入与存取主体要求存取的数据对应而设置的存取授权信息、以及一个控制单元，它从存取主体识别信息和存取授权信息获得一个存取授权，并根据所获得的存取授权控制存取主体对数据的存取。 The present invention provides a card type recording medium such as an IC card whereby the setting and modifying work of an access authority can be simplified and the management and operation of a security system can be reliably performed. The card type recording medium (1) contains storage units (2-1 to 2-n) to store data and an access control unit (4) to control an access to the data by an access subject. The access control unit (4) is designed to include an access subject identification information generating unit (5) to generate an access subject identification information for identifying the access subject, an access authority information read-in unit (6) to read in access authority information (3-1 to 3-n) set in correspondence with the data that the access subject requests to access, and a control unit (7) to obtain an access authority from the access subject identification information and the access authority information (3-1 to 3-n), and to control an access to the data by the access subject on the basis of the access authority obtained.
