Abstract: A system for storage on a magnetic record medium (tape or disc) of data with an extremely high packing density is described. Binary input information is encoded into a ternary signal for recording. That ternary signal has spectral properties which facilitate recording with extremely high bit packing density. The ternary signal also contains timing information. On playback the signal is decoded into binary coded ternary form. Timing information with respect to words of ternary data, as well as the individual terts which make up the works, is also derived. The system includes means for synchronizing the reproduced data in accordance with the timing information derived from the data itself, as well as with an external clock, and decodes the data into the original binary form.
Abstract translation: 描述了一种用于在具有非常高的堆积密度的数据的磁记录介质（磁带或盘）上存储的系统。 二进制输入信息被编码成用于记录的三进制信号。 该三元信号具有光谱性质，便于以极高的位封装密度进行记录。 三进制信号还包含定时信息。 在播放时，信号被解码为二进制编码的三元形式。 关于三元数据字的定时信息，以及构成作品的个人特征也得出。 该系统包括用于根据从数据本身导出的定时信息以及与外部时钟同步再现的数据的装置，并且将数据解码为原始二进制形式。
