Latest Patents

One of his latest patents is the "Deleted Data File Space Release System for a Dynamically Mapped Virtual." This system provides facilities in a dynamically mapped virtual memory data storage subsystem to immediately release the physical space occupied by a deleted dataset. It ensures data security by preventing unauthorized access to the data of scratched data files, both in cache memory and on the data storage devices. The system utilizes a user exit in the host processor data file scratch routine to transmit information to the data storage subsystem, indicating that the host processor is scratching a data file. This allows the data storage subsystem to concurrently scratch the data file from the virtual track directory and release the physical storage space.

Another significant patent is the "Read/Write Head Buffer." This invention provides a buffer memory for each read/write head in a rotating media data storage system. It allows a seek request from the processor to be handled as soon as the beginning of the requested data record is positioned below the associated read/write head. The data image stored on the rotating media is read and stored in the read/write head buffer, independent of the availability of a data communication path to the processor. This innovation ensures that the data retrieval time is efficient and maintains the integrity of the requested data.
