摘要： An information security system for tracing information outflow from a remotely accessible computer or computer network is disclosed. The system includes an internal communication system that has at least one internal computer for transmitting security information by tracing data through communication equipment, outputting the data to an external output means, and connecting the internal computer to an external network. A communication monitoring device stores information regarding the data that is to be transmitted by applying a security policy according to a security grade assigned to the destination to which the data is to be transmitted. The communication monitoring device is configured for extracting the identification of the destination from the transmitted data. It also includes a communication monitoring server for storing and displaying predetermined information about the data to be transmitted and for determining whether the tracing information is stored according to the security grade for the identified destination. A method of operating the disclosed system is also described.

摘要： A magnetic recording/reproducing apparatus without a need to adjust what is known as X-distance of an Audio/Control head. In one embodiment, the apparatus comprises a reference pulse generator, a delay control pulses generator, and a first and second delay circuits. The apparatus compares the phase of a reproduced control pulse with that of a generated reference pulse and phase-shifts the reproduced control pulse in order to synchronize both pulses. By synchronizing the pulses, the apparatus compensates for the deviation of the X-distance. Another embodiment may be implemented using a microprocessor.
