Abstract: Methods and arrangements are disclosed herein for optically storing data from a serial optical bit stream. As each bit of the optical stream is received it is applied to an optical storage medium e.g., lithium niobate, along with a reference beam. The angle of the reference beam is changed in synchronism with the received optical bits to create identifiable interference patterns for each bit.

Abstract: A method and arrangement for providing buffering and real time storage of high-speed data stream from internetwork of Wide Area Networks (WAN), Metropolitan Area Networks (MAN), and/or Local Area Networks (LAN) is disclosed. The exemplary apparatus comprises one or more parallel bus interfaces from Complex Programmable Logic Devices (CPLD) to buffer memory. The network data stream is directed through the CPLD where data compression takes place. The compressed data is stored (buffered) in memory buffers. Each memory buffer is associated with a hard disk drive via a PCI-X bus I/O controller. When the memory buffer is filled, input from the data network is directed to another RDRAM memory buffer. The content of each filled memory buffer is written to the hard disk drive associated with that buffer.
