摘要： A system for corrosion protection of a tape drive. The system includes: the tape drive; a humidity sensor for determining humidity information; a temperature sensor for establishing temperature information indicative of a temperature in an area of, or within, the tape drive; a heating entity for heating at least a portion of the tape drive; and a controller for activating the heating entity in a manner dependent on the temperature information established via the temperature sensor in order to prevent corrosion within the tape drive, the activating the heating entity being in response to a determination that the humidity information determined via the humidity sensor indicates that the relative humidity is above a specified relative humidity threshold value and the established temperature information indicates a temperature drop above a specified temperature drop value within a specified period of time.

摘要： A charge level for a first rechargeable power source, a second rechargeable power source, and a third rechargeable power source is determined. The first rechargeable power source is determined to be below a threshold level of charge. In response to determining that the first rechargeable power source is below a threshold level of charge, a switch is made from the first rechargeable power source to the second rechargeable power source.

摘要： A computer program product, including a storage device storing computer readable program code executable by a processor to implement a method for corrosion protection of a tape drive based on a tape drive corrosion protection system that includes a tape drive, a temperature sensor, a heating entity, and a controller. Humidity information is determined via a humidity sensor. Temperature information, indicative of a temperature in or within the tape drive, is established via the temperature sensor. The temperature information is received at the controller. The heating entity is activated in a manner dependent on the temperature information established via the temperature sensor in order to prevent corrosion within the tape drive. Activating the heating entity is in response to a determination that the relative humidity is above a specified relative humidity threshold value and a temperature drop is above a specified temperature drop value within a specified period of time.

摘要： A method and system for improving tape drive memory storage is provided. The method includes receiving, by a storage tape drive, a data stream for storage. The data stream is passed through a non-volatile memory device (NVS2) of the storage tape drive. The data stream is divided into adjacent variable length data chunks and a chunk list file including similarity identifiers for each of the adjacent variable length data chunks is generated and stored within a (non-volatile memory device) NVS1. Duplicate data including duplicated data with respect to a group of data chunks of the adjacent variable length data chunks is identified and deleted from the NVS2 of the storage tape drive such that the group of data chunks remains within NVS2. The group of data chunks is written to a data storage tape cartridge. Pointers identifying each data chunk and an associated storage position are generated and stored.
