  • Publication number: 20200089107
    Abstract: An embodiment of this disclosure provides a nano-imprinting method, including: applying an imprinting adhesive on a to-be-processed layer of a substrate located in an imprinting chamber; charging the imprinting chamber with a preset gas at a temperature higher than a boiling point of the preset gas, and pressing a nano-imprinting template on the imprinting adhesive; reducing an ambient temperature of the imprinting chamber to a temperature lower than the boiling point of the preset gas and maintaining the temperature for a preset time, such that the preset gas becomes a liquid; irradiating ultraviolet light from a side of the nano-imprinting template away from the imprinting adhesive to cure the imprinting adhesive; raising the ambient temperature of the imprinting chamber to be higher than the boiling point of the preset gas, such that the liquefied preset gas turns back into a gas; and demolding the nano-imprinting template from the imprinting adhesive.

  • Patent number: 10162712
    Abstract: The present invention provides systems and methods for extending media retention. Methods are provided in which a set of aging preferences are obtained. Data elements of a data set stored on storage media are evaluated against the aging preferences to determine whether each of the data elements satisfy the aging preferences. Each of the data elements that is determined to satisfy the aging preferences is aged. Aging can include freeing a portion of storage media, previously used to store a data element, for other storage usage.

  • Publication number: 20120185657
    Abstract: In one embodiment of the invention, a method is provided for retrieving certain electronic information previously stored on certain storage media after a threshold set in the storage retention criteria has been exceeded in an electronic information storage system that stores electronic information on storage media in accordance with a storage retention criteria is provided. The method includes storing a record in a memory associated with a system manager that assigns the storage retention criteria to the certain electronic data, designating the storage media available for overwrite after the threshold set in the storage retention policy has been exceeded, identifying the certain storage media available for overwrite, and retrieving information from the certain media after the threshold set in the storage retention policy has been exceeded.
