摘要： A recording apparatus for recording information signals on a recording medium is arranged to retain position information about the position of the recording medium relative to recording means obtained at the start of a recording action on the information signal and, when an instruction is given to make preparation for re-recording the information signal during execution of a previous instruction to bring a recording action to a pause, to bring, on the basis of the position information retained, the medium back to its positon obtained relative to the recording means at the start of the recording action. This arrangement facilitates a re-recording action on the information signal and permits effective use of the medium.
摘要翻译：用于在记录介质上记录信息信号的记录装置被布置成保留关于记录介质的位置相对于在记录动作开始时获得的记录装置对信息信号的位置信息，并且当给出指令进行准备时用于在前一指令执行期间重新记录信息信号以使记录动作成为暂停状态，根据所保持的位置信息将介质返回到相对于记录装置获取的位置录音动作。这种布置有利于对信息信号的重新记录动作并且有效地使用介质。
