Abstract: Techniques are described for reselling and/or refurbishing data tape media. The techniques may involve determining life information associated with a data tape medium and reselling the data tape medium when a remaining life of the data tape medium is larger than a pre-defined threshold. In this manner, the quality of resold magnetic tape can be improved, and the media can possibly marketed or warranted to the buyer based on the remaining life. In addition, refurbishing techniques are described that include degaussing of servo written data tape media, followed by the creation of new servo patterns on the degaussed media.

Abstract: A process for restoring magnetic recording tape damaged by “Sticky Shed” syndrome cleans magnetic tapes of the Backcoating which is causing their eventual degradation and destruction. The Backcoating is first removed in a multi-step process. A liquid cleaner, such as isopropyl alcohol, is applied to the Backcoating to dissolve it from and clean it off the Mylar Base. Before the liquid cleaner is applied, steps are taken to prevent the cleaner fluid from getting onto the Oxide side of the tape. The chemical cleaning is done as quickly as possible. The second step is to dry clean the Base surface of the tape to remove the remaining solvent and the debris of any remaining Backcoating. Then, the Oxide side of the tape is given a dry, non-chemical cleaning to remove the residue of contamination of the Backcoating which was deposited on the Oxide side of the tape as the result of physical contact with the Backcoating from the storage on the reel of tape. Once fully and properly cleaned, the tape is restored to a useful and long life. A machine is disclosed to carry out various mechanical and chemical actions involved in the inventive process in a safe and logical manner.

Abstract: A magnetic tape apparatus prevents dirt from being deposited on a magnetic tape even when the tape is repeatedly moved in a short interval. An operation monitoring unit calculates tape position from information supplied from a tape transport drive circuit and measures tape position from a previously stopped position as a reference point. The operation monitoring unit updates the reference point into a presently stopped position if the tape has moved from the reference point beyond a predetermined range and stopped, accumulates the number of times the tape has been stopped if the tape has moved from the reference point and stopped within the predetermined range, and instructs a control unit to transport the tape in a transported range greater than the predetermined range to bring an area on the tape into contact with a tape cleaner if the accumulated number of times exceeds a predetermined number of times.

Abstract: The device sprays a mist of cleaning fluid onto the record mediumnulle.g., motion picture filmnulland wipes it off, preferably with a soft material such as velvet. Then, the film is dried with air, including thin air jets to spread the liquid evenly, and heated, ionized air. The device has a closed housing and air in the housing is evacuated and sent to a still to recover much of the cleaning liquid and prevent its escape into the atmosphere.

Abstract: A method and apparatus for removing dust from a base film effectively so that electrostatic charges of the base film are reduced while the cleaning effect is kept high. After a cleaning solvent is applied onto one surface of a base film by a precoater, a rod member is pressed against the base film while the cleaning solvent remains on the base film, so that deposits on the base film are separated and scraped together with the cleaning solvent from the base film by the rod member. Just after the deposits are scraped from the base member, a solvent, of the same kind as the cleaning solvent or a mixture of a solvent of the same kind as the cleaning solvent and an additive mixed thereto, is applied onto the base film while the surface of the base film coated with the cleaning solvent is not exposed to an atmospheric air space.
