Mirage Data Recorder (MDR) - The  Ultimate in Seismic Recording

MDR is a virtual tape system combining the best of disk and tape technologies.  It is designed to provide seismic  data acquisition systems with a superior solution over existing conventional tape or disk solutions. MDR represents itself as a tape drive to data acquisition systems but utilizes disk drives as the primary recording media.

MDR operates seamlessly with all major data acquisition systems by emulating a variety of tape drives. MDR solutions are offered with a wide range of interfaces to allow connectivity to all seismic acquisition systems including older legacy systems.

MDR manages a pair of removable disk drives partitioned with multiple tape volumes as fault tolerant storage. It implements Ultera unique RAID for removable storage, allowing disk drives to be recorded to, removed, stored, reinserted, appended to, erased and returned to the field, while maintaining protection against accidental data erasure or data loss.  

 MDR provides complete assurance with Read after Write Real Time display of seismic data via an independent QC port. Seismic data is retrieved and displayed while the MDR recorder port is used to simultaneously record seismic files.

Embedded Tape Drive Archive accommodates applications requiring seismic files on tape cartridges. This function copies virtual tape cartridges to conventional tape cartridges at the full speed of tape drives.  Creates up to 4 tape cartridges. This feature supports creating tape cartridges simultaneously while recording or can be done at a later time.

MDR allows disk drives to be removed after recording sessions and reinserted for more recording if desired. It eliminates timely rebuild required by other NAS or RAID disk systems. MDR disk storage can be configured in seconds as opposed to several hours required by conventional RAID storage.

MDR Real Time QC Display

MDR maximizes performance by implementing a proprietary linear recording format as opposed to using the file system required by other disk based solutions.  Eliminating the file system reduces overhead and fragmentation of data files recorded on disk drives. MDR sustained recording performance exceeds 500GB/Hour.  MDR is perfect for high density 3D and 4D as well as continuous recording applications.

MDR is 100% compatible with Data Acquisition systems from Sercel, ION, ARAM, FairfieldNodal, and Hydroscience Technologies.
