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 the operation can be continued, corresponding to the current operating status and the remaining battery level, stored in the. 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 recording and playback apparatus, such as a CD-R/RW drive unit, 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 on the recording medium is prevented from being destroyed as a result of operation stopping due to, for example, the remaining battery level becoming zero.

Claims

1-22. -22. (canceled)

23. An information processing apparatus, comprising:

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 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 controlling a charge current in accordance with the power-supply information and a temperature of the battery.

24. An information processing system, comprising:

a recording unit configured to record data into a recording medium;

a power-supply unit configured to supply internal power by using a battery;

a power-supply information creation unit configured to create power-supply information including a remaining battery level; and

a control unit configured to record a file system onto the recording medium based on the power-supply information.
