索尼斯坎是一种新的全电子大容量存貯系统。这种存貯器是应用传播的声脉冲存取成批生产的薄膜存貯介质。存貯元件由两片磁致伸缩薄膜层组成,两片薄膜间夹一个导体。它们沉积在一片薄的玻璃基片上、并蚀刻成一个适当的图案。一个压电换能器连接在基片的一边缘。磁存貯元件的开关性能是由修改了的斯托纳——沃尔福斯(Stoner—Wohlforth)模型描述的,而声波的发生和传播是由一度传输线模拟来描述的。讨论了存貯元件的生产和操作。提出了10~7位存貯器系统的设计。制成了一个2048往的索尼斯炊存貯器的试验模型。它具有小于2微秒的存取时间,数字速率为每线长、每秒7兆位,存貯密度为每平方英时4000位。索尼斯坎体存貯是比较便宜的,因为存貯板可以成批生产;单个电子装置,卸换能器驱动开关,在写和读的过程中,成万位的半选;读出和记录的电子元件通过串联写读线,分配在许多平面中。可以期望在许多应用中,索尼斯坎将出电机械装置具有更引人的选择。
Sablescan is a new all-electronic mass storage system. This type of memory is a mass-produced thin film storage medium that utilizes the spread of acoustical pulses. The storage element consists of two magnetostrictive film layers, with a conductor sandwiched between the two films. They are deposited on a thin glass substrate and etched into a suitable pattern. A piezoelectric transducer is attached to one edge of the substrate. The switching performance of magnetic storage elements is described by a modified Stoner-Wohlforth model, and the generation and propagation of acoustic waves is described by a one-time transmission line simulation. Discusses the production and operation of storage elements. Proposed 10 ~ 7 bit memory system design. A test model of the 2048-to-Sony cooker was made. It has less than 2 microseconds of access time, a digital rate of 7 megabits per second and a storage density of 4000 bits per square inch. Sonicisk body storage is cheaper because the memory boards can be manufactured in batches; a single electronic device can be used to drive switch switches and switches to read and write tens of thousands of bits during writing and reading The electronic components are distributed in many planes by tandem write lines. It is expected that in many applications, Sogniscan will have an even more attractive alternative to electromechanical devices.
