摘要： Servo tracks for magnetic tape storage are written using two opposite polarities, rather than the one polarity normally used in servo tracks. Timing continues to be performed using only pattern members of like polarity, due to physical restraints, but the use of two polarities allows additional information to be encoded in the pattern more efficiently.

摘要： A servo stripe pattern for determining the longitudinal position of the tape with respect to the tape head. A data field on each frame of the servo pattern includes a digital one or a zero. An adjacent series of data fields are arranged in a predetermined sequence defining synchronization and position count fields. The position count field allows the tape controller to accurately determine where, along the length of the tape, the tape head is currently positioned.

摘要： A method of calibrating a servo reader and a read/write head for a data storage tape machine that reads and writes data to a data storage tape. The data storage tape has a servo pattern that is recorded on the tape in a known location. The servo pattern is used to provide precise position information for the data storage tape. According to the method, data is recorded on the data storage tape and the location of the data storage track is read. The location of the data storage tape is compared to the known location of the servo pattern to establish a reader offset value. The data storage tape machine is updated based upon the reader offset value to adjust the position of the read/write head.

摘要： In a magnetic recording device, a system and method for correcting errors in decoding a read data input signal. The system and method include multiple decoding channels, each channel processing the read data input signal and generating an output signal, where the output signal includes a data signal when no error is detected, and an error detection code when an error is detected. The system and method also include multiple error correction code (ECC) decoders, each decoder associated with and receiving the output signal of one of the channels and generating a corrected data signal when the received output signal is an error detection code and the error is correctable. The system and method further include a controller for selecting from the decoders one of the corrected data signals.

摘要： A method of generating an encoded signal from a sequential stream of digital data, where the encoded signal has a non-power carrying null state and a power carrying active state with two opposing polarities. Logical one bits are distinguished from logical zero bits by inverting the encoded signal's polarity at the start of only the logical one bits. The encoded signal is set to the active state during a bit set-up period before, and held in the active state during a bit hold period after each polarity inversion. At other times the encoded signal is set to the null state. The method may include the addition of equalization pulses during strings of consecutive logical zero bits to keep the encoded signal from remaining in the null state for extended periods. Each equalization pulse may be preceded by an equalization set-up period and followed by an equalization hold period where the encoded signal is in the active state. In the preferred embodiment the set-up periods, hold periods, and equalization pulse periods are one-third the duration period of the logical bits.
摘要翻译：一种从数字数据的顺序流生成编码信号的方法，其中编码信号具有非运行无效状态和具有两个相反极性的功率传送活动状态。逻辑1比特与逻辑0比特不同，仅在逻辑1比特的起始处反转编码信号的极性。编码信号在比特建立周期之前被设置为有效状态，并且在每个极性反转之后的比特保持期间保持在活动状态。在其他时间，编码信号被设置为零状态。该方法可以包括在连续的逻辑零比特串期间添加均衡脉冲以保持编码的信号在长时间内保持在空状态。每个均衡脉冲之前可以是均衡建立周期，随后是均衡保持周期，其中编码信号处于活动状态。在优选实施例中，建立周期，保持周期和均衡脉冲周期是逻辑比特的持续时间周期的三分之一。
