The major value-added network services operator Internet Inc has developed a floppy disk transfer device that conforms to Nippon Telegraph & Telephone Corp’s ISDN service: the device works by copying data on one disk to a disk in another drive, which can be thousands of miles away at the end of an ISDN line; the cost of sending one floppy disk of data near instantaneously between Tokyo and Osaka will drop to around $3; the disk drive is called the DIX-ISDN, and was developed jointly with the communications equipment manufacturer ED Contrive Corp (yes, really).
