Abstract

The invention relates to an information recording apparatus capable of relay recording, during which a sequence of data is continuously recorded across a plurality of recording media, as well as to a controlling method thereof. If the relay recording mode is set, it is determined whether any medium having a wireless communication function is present among the recordable recording media. If a recording medium having a wireless communication function is present, data transfer utilizing the wireless communication function is inactivated. This enables relay recording that accounts for cases in which memory cards provided with a wireless communication function are included among the recording media.

Claims

1. An information recording apparatus having a relay recording mode in which a sequence of data is recorded across a plurality of recording media, comprising:

an identification unit that identifies a recording medium having a wireless communication function among recordable recording media being attached to the information recording apparatus, wherein the recording medium having the wireless communication function is capable of transmitting data to an external apparatus through the wireless communication function, the external apparatus being other than the information recording apparatus and any recording medium being attached to the information recording apparatus;

a wireless control unit that controls the wireless communication function of the recording medium having a wireless communication function; and

a main control unit that controls the wireless control unit;

wherein the main control unit controls the wireless control unit, in the case that the relay recording mode is set, to inactivate data transfer utilizing the wireless communication function for the recording medium having a wireless communication function identified by the identification unit; and

wherein the main control unit controls the wireless control unit, in the case that the relay recording mode is not set, not to inactivate data transfer utilizing the wireless communication function for the recording medium having a wireless communication function identified by the identification unit.

2. The information recording apparatus according to claim 1 wherein, in the case that the relay recording mode is set and a recording medium having a wireless communication function identified by the identification unit is a recording medium initially used in the relay recording mode, the main control unit does not inactivate data transfer utilizing the wireless communication function for that recording medium.

3. The information recording apparatus according to claim 1, wherein the main control unit is configured to control the wireless control unit to activate inactivated data transfer utilizing the wireless communication function in the case that recording in the relay recording mode ends without the sequence of data recorded in the relay recording mode spanning across a plurality of recording media.

4. The information recording apparatus according to claim 1, wherein the sequence of data is captured video data.

5. The information recording apparatus according to claim 1, wherein the plurality of recording media includes a plurality of memory card.

6. The information recording apparatus according to claim 1, wherein the plurality of recording media includes a memory card and a built-in memory.

7. The information recording apparatus according to claim 1 further comprising an image sensor.

8. The information recording apparatus according to claim 1, wherein the information recording apparatus is digital video camera.

10. A non-transitory computer-readable recording medium which stores a program which, when run on a device, causes the device to function as each unit provided in the information recording apparatus according to claim 1.

9. A method for controlling an information recording apparatus having a relay recording mode in which a sequence of data is recorded across a plurality of recording media, and comprising a wireless control unit that controls any wireless communication function that the recording media are equipped with,

the method comprising the steps of:

identifying a recording medium having a wireless communication function among recordable recording media being attached to the information recording apparatus, wherein the recording medium having the wireless communication function is capable of transmitting data to an external apparatus through the wireless communication function, the external apparatus being other than the information recording apparatus and any recording medium being attached to the information recording apparatus; and

controlling the wireless control unit, in the case that the relay recording mode is set, to inactivate data transfer utilizing the wireless communication function for the recording medium having a wireless communication function identified in the step of identifying step, and

wherein the step of controlling further controls the wireless control unit, in the case that the relay recording mode is not set, not to inactivate data transfer utilizing the wireless communication function for the recording medium having a wireless communication function identified in the step of identifying.
