摘要： A system and method for decoding magnetic media. Parallel decoders, each with a different equalization magnitude, are used to decode a read signal. A Viterbi metric is used to determine the direction and magnitude of equalization shift that best compensates for a systematic separation, such as pole tip recession. If optimal equalization has changed, the equalization coefficients of the decoders is shifted to compensate.

摘要： A method and apparatus for allowing communication between a stationary circuit and circuitry in motion with respect to the stationary circuit is presented. Communication is achieved and verified by transmitting a clock signal and a control signal in synchronization with the clock signal over separate clock and control transformer channels between the stationary circuit and the moving circuitry.

摘要： The present invention describes a method and system for adjusting the rate of data transfer between a high-speed multi-channel tape drive and a slower-capability network interface. The present invention allows for selectively enabling/disabling active channels to adjust the data throughput to match the data transfer capabilities of the network interface. Such an adjustment optimizes the rate of data transfer between the system and the tape drive by reducing the amount of stop and start operations normally present in an environment where the network interface cannot support the high-speed data transfer rates of a tape drive. Such an enablement/disablement adjustment system allows for a greater range of varying data rates within the transfer.
摘要翻译：本发明描述了一种用于调整高速多通道磁带驱动器和较慢能力的网络接口之间的数据传输速率的方法和系统。本发明允许选择性地启用/禁用活动信道来调整数据吞吐量以匹配网络接口的数据传输能力。这样的调整通过减少网络接口不能支持磁带驱动器的高速数据传输速率的环境中通常存在的停止和启动操作的量来优化系统和磁带驱动器之间的数据传输速率。这种启用/禁用调整系统允许在传送内的更大范围的变化的数据速率。
