一、概述9404型软盘驱动器(如照片所示)是一种利用单片可换软盘作为存贮介质的廉价、高可靠随机存取的存贮装置。该装置可使用硬扇区或软扇区两种类型的介质盘片。9404型软盘驱动器适用于许多方面,如:智能终端、可编程序计算器、电子测试设备、文字符号处理器、小型商业系统、计算机程序和数据存贮器、成批处理终端存贮器、键盘一软盘输入装置及许多其他小系统,例如:IBM系统/32型廉价存贮器等。
I. Overview The Model 9404 floppy disk drive (shown in the photo) is a low-cost, highly reliable random-access memory device that uses a single-chip, changeable floppy disk as a storage medium. The device can use hard or soft sectors of both types of media disc. The Model 9404 floppy disk drive is suitable for many applications such as: intelligent terminals, programmable calculators, electronic test equipment, word processors, small business systems, computer programs and data storage, batch processing of terminal memories, keyboards A floppy disk drive, and many other small systems such as the IBM System / Type 32 low-cost memory.
