摘要： By reducing the number of seek operations in an operation to play back a signal from a recording medium, the amount of data temporarily stored in a read buffer memory employed in a signal recording/playback apparatus is large enough to be output as a playback signal during a seek operation, allowing a continuous playback operation to be carried out. In order to reduce the number of seek operations, a signal is always recorded onto the recording medium in continuous free areas each having a size equal to or larger than a predetermined recording/playback time length which is typically set at 1 minute. If it is necessary to insert an additional signal having a length smaller than the predetermined recording/playback time length into a point of insertion in an area already occupied by an existing signal, a continuous free area with a size equal to or larger than the predetermined recording/playback time length is newly allocated to the additional signal. The additional signal is then recorded in the free area instead of being inserted into the point of insertion. Since the free area is larger in size than the length of the additional signal, the rest of the free area is filled up with a portion of the existing signal adjacent to the point of insertion.

摘要翻译： 通过减少用于从记录介质播放信号的操作中的寻道操作次数，临时存储在信号记录/重放装置中使用的读缓冲存储器中的数据量足够大以作为重放信号被输出 搜索操作，允许执行连续播放操作。 为了减少搜索操作的数量，信号总是被记录在连续空闲区域中的记录介质上，每个区域的大小等于或大于通常设置为1分钟的预定记录/重放时间长度。 如果需要将具有小于预定记录/重放时间长度的长度的附加信号插入到已经被现有信号占据的区域中的插入点中，则具有等于或大于预定记录/重放时间长度的尺寸的连续空闲区域 记录/播放时间长度被新分配给附加信号。 然后将附加信号记录在空闲区域中，而不是插入插入点。 由于空闲区域的尺寸大于附加信号的长度，所以剩余的空闲区域被填充有与插入点相邻的现有信号的一部分。

摘要： A video signal recording/reproduction apparatus utilizes time division writing and reading to implement simultaneous recording and reproduction of different video signals to and from a common recording medium. In one operating mode, a first video signal being recorded and a second video signal being reproduced are simultaneously displayed in separate windows on a display. In other operating modes, two or more video signals are simultaneously recorded or reproduced to/from a common recording medium, and simultaneously displayed in separate windows.
