Information processing system and information processing apparatus
First Claim
1. An information processing system comprising:
- an information processing apparatus including;
a recording and/or reproducing unit for recording data into a recording medium and/or for reading data from the recording medium;
a power-supply unit capable of supplying internal power by using a battery;
a power-supply information creation unit for creating power-supply information in which remaining battery level information about said power-supply unit is stored; and
a control unit for performing a control process for limiting a data recording operation in such a manner as to comply with each recording method which is possible by said information processing apparatus in accordance with the remaining battery level information, which is obtained based on the power-supply information.

Abstract
Battery information is transmitted from a recording and playback apparatus to a host computer. In the host computer, based on the time for which operation can be continued, corresponding to the current operating status and the remaining battery level that is included in stored battery information, a warning is output, the data of a cache memory is written, data writing prohibition is set, and a forced closing process is performed. With this construction, in a system formed of a portable recording and playback apparatus and a personal computer, a proper system operation corresponding to the remaining battery level of the recording and playback apparatus is obtained, and the data recorded in the recording medium is prevented from being destroyed as a result of operation stopping due to, for example, the remaining battery level becoming zero while recording.
