    • An information storage system utilizing an acoustic medium having its surface subdivided into a plurality of individually isolated acoustic transmission channels upon which a plurality of transmit and receive transducers are selectively placed. Each respective transmit transducer is electrically excited by a signal containing information from at least a preselected one of a plurality of data sources in order to cause a resultant acoustic stress wave to be propagated upon the surface of the medium within the associated acoustic transmission channel until the resultant stress wave is converted by an associated receive transducer into a plurality of charges which, in turn, are applied to a data source which, on command, either selects a new data to be stored or the old data that was circulated to be reconstituted into a transmit format to be recirculated within the associated acoustic transmission channel of the system.
    • 一种利用声学介质的信息存储系统,该声学介质的表面被细分为多个单独隔离的声学传播通道,多个发射和接收换能器选择在该传播通道上。 每个相应的发射换能器由包含来自多个数据源中的至少预选的一个数据源的信息的信号电激励,以使得所产生的声应力波在相关的声传输通道内的介质的表面上传播,直到 合成的应力波由相关的接收换能器转换成多个电荷,这些电荷又被施加到数据源,数据源根据命令选择要被存储的新数据或被重新构建成循环的旧数据 在系统的相关声传播通道内循环的发送格式。
