Segrate, 5 maggio 2003 - Grazie alla stretta collaborazione tra gli scienziati di Imation e Nasa, è stato possibile pulire e stabilizzare nastri magnetici utilizzati sul Columbia Shuttle e recuperati dall´Orbiter Experiment Support System (Oex) data recorder. L´accurata operazione, condotta dall´Imation Data Recovery Team, ha permesso alla Nasa di accedere ai dati dello Shuttle Colombia in meno di 4 giorni. Durante l´ispezione è stato rilevato che il nastro era danneggiato sia nella porzione iniziale sia in quella finale, inoltre la parte centrale risultava contaminata, probabilmente a causa dello sporco e dell´acqua. Dopo aver identificato il punto in cui la strumentazione ha smesso di registrare dati, il team Imation è stato in grado di equilibrare le condizioni del nastro, pulirlo e renderlo stabile in modo da poter recuperare i dati contenuti, evitando possibilità di errori.Imation Corp., a worldwide leader in data storage, on March 26th has announced that it has completed the cleaning and stabilization of the magnetic instrumentation tape recovered from the space shuttle Columbia´s salvaged rbiter Experiment Support System (Oex) data recorder. The recorder, which stores sensor information about temperature, aerodynamic pressure, vibrations and other data from hundreds of sensor locations on the orbiter, operates only during launch and re-entry. The Oex uses magnetic tape to record data that is not sent to the ground by telemetry. Working for Nasa (National Aeronautics and Space Administration) and the Columbia Accident Investigation Board (Caib), Imation´s role had previously been identified by Nasa. The Oex recorder, which had been recovered Wednesday in Texas, was delivered to Imation´s Discovery Technology Center by Nasa officials on Friday. Imation scientists worked over the weekend to inspect and evaluate the tape. The visual inspection was conducted using a proprietary non-destructive process based on Imation´s extensive recording experience that enabled Imation scientists to pinpoint the place on the tape where it had stopped recording instrument data. In consultation with Nasa officials, they developed a process for cleaning and stabilizing the tape, which began on Monday and concluded Tuesday. The cleaning process required Imation scientists to immerse the tape in filtered, deionized water by hand, then dry it. The tape was delivered to Nasa on Tuesday for transfer to the Kennedy Space Center in Florida where playback and dubbing of the data onto a new tape will occur. According to Nasa, the freshly-dubbed tapes will be sent to Johnson Space Center in Houston and other facilities where analysis of the data by Nasa and the Caib will occur. "Imation is proud to employ our capabilities, facilities and expertise to help Nasa and the Caib as they search for the cause of the Columbia tragedy," said Frank Russomanno, president, Imation´s Data Storage and Information Management business. " Imation´s data recovery expertise grows out of our core competency built over 50 years in developing and manufacturing data storage removable media. Our Discovery Technology Center, housing more than 300 technology scientists, is the only research and development facility in the United States focused solely on removable data storage media." Following are answers to frequently asked questions concerning Imation´s role in assisting Nasa and the Caib What has Imation´s role been with the Orbiter Experiment Support System (Oex)? Imation has been working with the Nasa team to clean and stabilize the instrumentation tape recovered last Wednesday from the space shuttle. Imation has worked in close interaction with Nasa to prepare the tape so that Nasa and the Columbia Accident Investigation Board can recover and evaluate the data on the tape. |
