Abstract: Embodiments of the present disclosure provide a method, device and computer program product for managing backup data. The method comprising: obtaining historical information of a plurality of historical operations on target data in a backup storage device during a first time period, the historical information indicating at least types and time of occurrences of the plurality of historical operations; determining, based on the historical information, whether the target data is to be rewritten to the backup storage device within a second time period after the first time period; and in response to determining that the target data is to be written to the backup storage device within the second time period, adjusting an expiration time of the target data in the backup storage device. Based on such a manner, efficiency of the backup system can be increased.

Abstract: A method to manufacture magnetic recording medium including the step of subjecting the unfinished magnetic recording medium to a random orientation device prior to a drying step, to thereby remove the magnetic anisotropy of the magnetic recording medium caused by the preferential orientation of ferromagnetic fine particles along the travelling direction of the unfinished magnetic recording during the application of a magnetic coating composition onto a non-magnetic support strip. The random orientation device includes a magnet, which is oriented parallel to the plane of the non-magnetic strip and generates a set of lines of magnetic field. Each set of lines of magnetic fields are associated with only one magnet and contain both forward and backward directional magnetic fields in a direction perpendicular to the travelling direction of the unfinished magnetic recording medium. More than one magnet can be used; however, each magnet generates a separate and independent set of such lines of magnetic field.
