2. Description of the Related Art There is a demand for recording and storing video data which is photographed by an image pickup device such as a television camera and recorded on a video tape in such a manner that information such as its contents can be easily confirmed. . Especially,
In the case of a television broadcast station used for news gathering, a necessary cut is quickly selected from a large number of cuts (consecutively shot images or video data) shot by a video camcorder or the like. Need to be edited.

Until now, usually, such information of recorded video data is recorded in a separate memo at the time of shooting, and at the time of reproduction or editing, desired video data is selected at a high speed while viewing the memo. Such a method is used. In recent years, in a 1/4 inch digital video cassette tape or the like, a semiconductor memory element such as a flash memory is incorporated in a cassette for accommodating a video tape so that information such as recording time, recording content, and title can be recorded. There are also things.

However, recording and reproduction of data with respect to the semiconductor memory device incorporated in such a video cassette tape is provided, for example, near the erroneous erasure prevention claw on the back of the cassette case, and ground, power, clock, It is performed by a contact method through four electrodes of data, and therefore, there are some disadvantages.
