摘要： A system for controlling movement of a head over tracks on a disc in a disc drive includes a servo positioner for positioning the head over a desired track, a sectoring circuit for determining when the head is over a data sector on the desired track, a formatter for controlling data transfers to and from the desired track, and a controller for providing the servo positioner with a track address indicative of the desired track. A track change system is coupled to the formatter and the servo positioner, and provides a direct communication channel between the servo positioner and the formatter. Thus, the data transfer can be carried out utilizing communications between the formatter and the servo positioner, without waiting for the microcontroller to be interrupted.
摘要翻译：用于控制磁头在磁盘驱动器盘上的磁道上的磁迹的移动的系统包括用于将磁头定位在期望的磁道上的伺服定位器，用于确定磁头何时位于期望磁道上的数据扇区上的扇区电路，格式器用于控制往返所需轨道的数据传输，以及用于向伺服定位器提供指示期望轨道的轨道地址的控制器。轨道更换系统耦合到格式器和伺服定位器，并且在伺服定位器和格式器之间提供直接的通信通道。因此，可以利用格式化器和伺服定位器之间的通信来执行数据传输，而不必等待微控制器被中断。

摘要： A system and method for accessing data stored on surfaces of discs in a disc drive utilizing more than one serpent per recording zone. The serpents are traversed using a defect descriptor table and one or more physical zone tables (PZTs). An Address Translation Logic Unit is configurable to use one or more PZTs to access multiple serpents per recording zone.
