    • A recording apparatus for facilitating data erasure operations involving data recorded on a recording medium. Each piece of data recorded on the recording medium may be examined to determine whether it is rerecordable by determining whether the data is already stored in another storage medium. When data erasure is requested, erasure processing may be controlled in accordance with the result of the determination. For example, original data based on data captured by a microphone or a camera (namely, non-rerecordable data) may not be erased (without specific approval by the user). Conversely, rerecordable data copied from another recording medium such as a CD may be erased.
    • 一种用于促进涉及记录在记录介质上的数据的数据删除操作的记录装置。 可以检查记录在记录介质上的每条数据,以通过确定数据是否已经存储在另一存储介质中来确定是否可重新记录。 当请求数据擦除时,可以根据确定的结果来控制擦除处理。 例如,基于由麦克风或摄像机捕获的数据(即不可重新记录的数据)的原始数据可能不被擦除(未经用户的特别许可)。 相反,可以擦除从诸如CD的其它记录介质复制的可重新记录的数据。
