摘要： An apparatus and a method of stopping a spindle motor for rotating a composite disk in a disk player. The composite disk contains a first area having information recorded thereon at a first rotational frequency, and a second area having information recorded thereon at a second rotational frequency which is greater than the first rotational frequency. The spindle motor is stopped when a stop or eject command is instructed during or after information is read from the second area of the composite disk by moving a pickup for reproducing information recorded on the disk to the first area and supplying a counter torque brake signal to the spindle motor, thereby slowing the rotational frequency of the disk to a rotational frequency in which information can be read from the first area. A further counter torque brake signal is supplied to the spindle motor for a predetermined amount of time after the moved pickup begins to read information recorded on the first area to thereby stop the rotation of the composite disk.

摘要翻译： 一种用于使主轴电动机停止在盘播放器中旋转复合盘的装置和方法。 复合盘包含第一区域，其具有以第一旋转频率记录在其上的信息，第二区域具有以大于第一旋转频率的第二旋转频率记录的信息。 当通过将用于再现记录在盘上的信息的拾取器移动到第一区域时，在从复合盘的第二区域读取信息之间或之后指示停止或弹出命令时，主轴电动机停止，并且将反转矩制动信号提供给 主轴电动机，从而将盘的旋转频率减慢到可以从第一区域读取信息的旋转频率。 在移动的拾取开始读取记录在第一区域上的信息，从而停止复合盘的旋转之后，进一步的反向转矩制动信号被提供给主轴电动机一段预定的时间。
