Provided are a recording device, a recording method and a program capable of recording a plurality of types of data files and reproducing, even when data recording is interrupted, data that have been recorded before the interruption. The recording device includes a recording medium control unitfor controlling recording and reproduction of data on a recording mediumincluding a data area in which data rows can be recorded as files and a specific area in which management information for the files can be recorded, and a recording control unitfor time-divisionally recording, through the recording medium control unit, a first data row as a first file and a second data as a second file. The recording control unitreserves an area in the data area and records the first data row in the reserved area in sequence, and when switching from the first data row to the second data row for recording, the recording control unitrewrites the management information corresponding to the end of the first file recorded in the reserved area immediately before the switching such that the first file ends at the end and records the second data row from a location subsequent to the end of the first file in the reserved area.

Recording device, recording method and program

A cooking device includes a control mode switch selecting a control mode for controlling a heating operation; a setting switch for selecting a set value in each control mode; a heating control unit for controlling a heating unit based on the control mode and the set value inputted through the control mode switch and the setting switch; and a selection switch for selecting the operation mode. The operation modes include a first operation mode in which all of the plurality of control modes are set to be selectable and a second operation mode in which only part of the control modes are set to be selectable. The heating control unit disables at least one control mode switch when the second operation mode is selected by the selection switch.

Cooking device

A wireless communications control system includes: a data server; a base station; and a plurality of wireless terminals, each exchanging data communications with the data server by establishing wireless communications with the base station. Each wireless terminal includes a control section for generating property information representing own property and a wireless communications section for transmitting that property information to the base station. The property information includes at least one of information indicating operating status of the wireless terminal, information identifying the wireless terminal itself, and information identifying the user of the wireless terminal. The data server includes a communications section for receiving the property information from the respective wireless terminals by way of the base station and a control section for choosing, by reference to the property information received, one of the wireless terminals to exchange the data communications with. The control section of the data server exchanges the data communications with the wireless terminal chosen.

Wireless communication control system and method thereof

The file recording method of the present invention is a method for recording a file on an information medium including at least both a specific area and a data area. In the method, a reserved area is allocated previously as a part of a recording file, from a current recording location of the recording file under recording on the data area, and at the same time, management information of the recording file including the reserved area is recorded on the specific area. When recording data additionally on the recording file, the data are recorded on the reserved area from the recording location. Thereby, the concentration of rewriting of the management information of a file system to a storage area is avoided while compatibility with an existing file system is maintained, and thus the life of the information medium is extended.
