摘要： Apparatus and method for write delay stabilization. A write driver is adapted to output bipolar write currents to write data to a memory. A preconditioning circuit is adapted to output first and second thermal preconditioning currents through the write driver to stabilize a write delay associated with the write driver to a steady-state level prior to the writing of data to the memory.

摘要： Apparatus and methods are provide for frame synchronization and clock and data recovery. In an example, a method can include receiving initial data of a stream of information, sampling the stream of information a plurality of times per unit interval to provide a plurality of sample intervals, integrating transition information for each sample interval, and selecting a sampling phase to sample each symbol of the stream of data using the integrated transition information.

摘要： This disclosure is related to measurement of latency in data paths. A latency measurement may be accomplished by calculating a roundtrip write-to-read latency based on generating a write signal and receiving a read signal approximately simultaneously. The read signal may be based on a coupling between a write element and read element. A device setting may then be adjusted based on the calculated roundtrip write-to-read latency. Further, a read/write mechanism that is used to write user data to and read user data from a data storage medium may be used to determine the roundtrip write-to-read latency. Even further, the roundtrip write-to-read latency may be determined in real-time as the data storage device is in operation.
摘要翻译：本公开涉及数据路径中的等待时间的测量。可以通过基于产生写入信号和大致同时接收读取信号来计算往返写入读取延迟来实现等待时间测量。读取信号可以基于写入元件和读取元件之间的耦合。然后可以基于所计算的往返读写延迟来调整设备设置。此外，可以使用用于将用户数据写入数据存储介质并从用户数据存储介质读取用户数据的读/写机制来确定往返读写延迟。更进一步地，当数据存储设备正在运行时，可以实时地确定往返写入延迟。
