In step S202, sensor invalidation processing is sequentially executed for each entry in the list. In step S203, sensor invalidation processing is sequentially executed until it is determined that there are no unprocessed entries in the sensor list. In the case of this example, as shown in FIG. 4A, the HDD-compatible sensors are the temperature sensor 1, the humidity sensor 2, the acceleration sensor, the impact sensor, and the atmospheric pressure (altitude) sensor. Processes are executed sequentially. By this invalidation process, the power supply to these sensors is stopped or reduced. In addition, the sensor information about the invalidated sensor is registered in the sensor status list. For example, the sensor status list shown in FIG.

  As shown in FIG. 4B, the sensor status list records invalidated sensor identifiers corresponding to the respective recording media. In the sensor validation process, the sensor validation process, that is, the power supply process is executed with reference to the sensor list or the sensor status list.

  In step S <b> 402, the control unit sequentially executes a process of enabling the HDD-compatible sensors according to the list entries in accordance with the information acquired from the memory. In step S403, sensor validation processing is sequentially executed until it is determined that there are no unprocessed entries in the sensor list. In the case of this example, as shown in FIG. 4A, the HDD-compatible sensors are a temperature sensor 1, a humidity sensor 2, an acceleration sensor, an impact sensor, and an atmospheric pressure (altitude) sensor. Processes are executed sequentially. By this validation processing, power supply necessary for sensor operation is started for these sensors, and sensor detection information is input to the control unit.

Alternatively, the processing sequence to be reduced will be described. This process is also executed under the control of the control unit 104 in the apparatus shown in FIG. First, in step S501, access destination (recording destination or playback source) information is input. This information is, for example, information determined by user input from the operation unit 105, program control that automatically executes recording medium determination processing in accordance with attachment / detachment or activation processing of various media, and the like.

  In step S502, the control unit creates a list of accessible media or acquires it from the memory. This is the media list shown in FIG. The media list shown in FIG. 8 is a list in which media numbers, media types, invalidation sensor identifiers, sensor validation processing information, and sensor invalidation processing information are associated as entries corresponding to the recording media. The invalidation sensor identifier is identification information of a sensor corresponding to each medium, and the sensor validation processing information is information applied to sensor validation, for example, a program executed in the sensor validation processing, an application parameter, a usage register, etc. Information, or information applied to access to such information.

In step S504, the control unit determines whether the entry corresponds to the selected medium selected as the access destination. If it is determined that the entry corresponds to the selected medium, the process proceeds to step S505, where it is determined whether the entry check of all the media lists has been completed. If there is an unprocessed entry, the process returns to step S503, The process for the process entry is executed.

  If it is determined in step S504 that the entry is not compatible with the selected medium selected as the access destination, the process proceeds to step S511, and a process for invalidating the sensor corresponding to the non-selected medium not selected as the access destination is executed. In, the invalidated sensor information is written in the media list. That is, a process of writing necessary information such as invalidation sensor identifier, sensor validation process information, sensor invalidation process information, etc. in the media list is executed. Thereafter, in step S505, the same processing is repeatedly executed until the entry check of all media lists is completed.

  By this process, the sensor state corresponding to the media that can be used in the information processing apparatus and information necessary for the validation process and the invalidation process are updated and stored in the memory. When each sensor is returned from the standby state to the accessible state to enable the sensor, processing using this media list is executed. With reference to the flowchart shown in FIG. 9, a sensor-enabled processing sequence for media is described. This process is also executed under the control of the control unit 104 in the apparatus shown in FIG.

In step S604, the control unit determines whether the entry corresponds to the medium selected as the medium for executing the transition process from the standby state to the access state. judge. If it is determined that the entry is not compatible with the selected medium, the process proceeds to step S605, where it is determined whether or not the entry check of all the media lists has been completed. Execute the process for the entry.

  If it is determined in step S604 that the entry is compatible with the selected medium, the process proceeds to step S611 to acquire information set in the corresponding entry in the media list, and in step S612, the sensor activation process corresponding to the selected medium is performed.
