IPC: G06F21/62
Filed: 1990-11-27
Abstract: PURPOSE:To properly protect the information stored in a recording medium by comparing the protection information given from a 2nd recording medium individual to an operator with the protection information stored in a 1st recording medium and allowing an access to only a logical recording medium (partition) that is specified by the protection information given from the 2nd recording medium. CONSTITUTION:The storage area of a magneto-optical disk is provided with a partition control information area 201, a protection information area 202, and the user areas A1 - An which are divided with partitions. The area 202 stores the protection information which specifies the operator of each partition. When an access is applied to the magneto-optical disk, the contents recorded on a magnetic card which is controlled by each operator as the 2nd recording medium are compared with the contents of the protection information on the magneto-optical disk. When no coincidence is obtained between both contents, the occurrence of an error is displayed. Thus the information stored in the recording medium can be properly protected against the accesses given from the outsiders.

IPC: G11B15/02
Filed: 1988-12-23
Abstract: PURPOSE: To prevent loss of time and to shorten search time by reducing the traveling speed of a recording medium each time its traveling direction is switched in both forward and backward directions and generating a report signal indicating retrieval of a target position when it is passed last. CONSTITUTION: In a retrieval method to be applied to a data recorder, which records and reproduces for example a data from a computer 3 using a rotary head type digital audio tape recorder(DAT) 1 in accordance with DAT format, the traveling speed is reduced of a recording medium 15 such as a magnetic tape, with its position detected while the medium 15 is run alternately in both forward and backward directions, with a report signal generated indicating a search completion immediately after a target position is passed last, and the target position is thereby detected. Consequently, there is no waiting time in which the recording medium is at a standstill, with the report signal generated immediately when the target position is sensed. Thus, with the recording medium 15 traveling, the next command signal can be received, reducing the retrieval time.
