    • An information signal recording system arranged to divide original information signals into signal groups, each bearing a predetermined amount of information, to have a plurality of compressing modes for different information compressing ratios and to compress the information signals of each group in one of the different compressing ratios in recording these signals on a tape-shaped magnetic recording medium comprises first compressed information signal forming assembly which operates on all these groups to form and produce a first compressed information signal consisting of only the information signals of a specific part of each of these groups; second compressed information signal forming assembly which operates on some of these groups to form and produce a second compressed information signal consisting of information signals of each groups excluding the information signals of the specific part; a magnetic head which records signals on the tape-shaped magnetic recording medium by tracing the medium in a direction of crossing the longitudinal direction of the medium; and supply assembly for supplying the magnetic head with the first and second compressed information signals by switching them from one over to the other at every half of the medium tracing period of the magnetic head.
    • 一种信息信号记录系统,被布置成将原始信息信号分成信号组,每个信号组具有预定量的信息,以具有用于不同信息压缩比的多个压缩模式,并且在不同压缩之一中压缩每个组的信息信号 在带状磁记录介质上记录这些信号的比率包括第一压缩信息信号形成组件,其对所有这些组进行操作以形成并产生仅由这些组中的每个组的特定部分的信息信号组成的第一压缩信息信号 ; 第二压缩信息信号形成组件,其对这些组中的一些组进行操作以形成并产生除了特定部分的信息信号之外的每个组的信息信号组成的第二压缩信息信号; 磁头,其通过在与介质的纵向交叉的方向上跟踪介质来在带状磁记录介质上记录信号; 以及供应组件,用于通过在磁头的介质追踪周期的每半个将它们从一个切换到另一个来向磁头提供第一和第二压缩信息信号。
