Latest Patents
One of Ruska's latest patents is a high-capacity tape drive that transparently writes and reads large packets of data. This invention features a tape packet assembler/disassembler (TPAD) that accumulates host-transmitted records, which may or may not be blocked by the host. The TPAD combines these records into packets that consist of a data portion made up of data blocks and a trailer portion containing table entries that describe how to disassemble the packet. The TPAD intercepts host-transmitted commands to write a tape mark and replaces them with corresponding information in the trailer. Packets are accumulated in a buffer and written to the tape drive when the buffer is full or upon a command from the host to reposition the tape. This innovative approach results in a considerable increase in the efficiency of tape utilization, as the interblock gaps that would ordinarily separate the host-transmitted records now separate packets. Additionally, the TPAD maintains various pointers in the trailer to assist in forward and back spacing by file and records. It can also automatically and adaptively compress and decompress the user's data, further enhancing its functionality.
