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, said 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 tape drive system for ensuring tape data integrity by tape surface inspection, the tape drive system being configured for reading and writing data from/to a magnetic tape, is provided. The tape drive system includes a laser inspection unit comprising a sender and a receiver integrated into the tape drive system, wherein the laser inspection unit configured for recognizing a tape defect by scanning the magnetic tape when the tape drive system is in operation. The tape drive system includes a read/write head configured for acting together with the laser inspection unit as sensors for providing sensor data during a read/write operation of the tape drive system, a communication link between the sensors and a controller unit for exchanging sensor data. The controller is configured for evaluating sensor data and for triggering predefined actions based on the respective evaluation results such that the tape data integrity is ensured.

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.

Duplicate data chunks of the data stream are identified and deleted such that a group of data chunks remain in a non-volatile memory device (NVS2) of the storage tape drive. The group of data chunks is written to a data storage tape cartridge. Pointers are generated and stored within the data storage tape cartridge. The pointers are associated with a location within an NVS1 for storing de-duplication hashes identifying each data chunk of the group of data chunks stored within data storage tape cartridge. The de-duplication hashes are written by from the NVS1 to a manager non-volatile memory device (MNVS) of a storage tape drive hardware library system. The MNVS is updated.

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 tape drive includes a plurality of rollers, a head, a tension sensor, and control circuitry. The rollers are spatially arranged within the tape drive to define a route for tape of a received data cartridge to travel from the received data cartridge to a tape reel. The head includes read elements and write elements configured to read from and write to the tape as tape of the received data cartridge travels along the route. The tension sensor is configured to measure tension of the tape as it travels along the route. The control circuitry is configured to cause a motor to impact the tension to keep the tape within a tension threshold.

摘要： A tape drive system as a Network Attached Storage (NAS) device and a method for operating the tape drive system. A tape drive is connected to a native connector disposed in a wall of a housing. The native connector enables an external connection to the tape drive. A single board computer is operated in a dimension of a credit card. The single board computer includes at least one integrated communication interface selected from Wi-Fi, Ethernet, USB, and combinations thereof. Data is transferred to and from the tape drive via the at least one integrated communication interface, wherein if the at least one integrated communication interface includes Ethernet and/or USB, then a connector related to the Ethernet and/or USB is provided in a wall of the housing. The tape drive, the single board computer, the native connector and the related connector are provided in the housing.

摘要： A data storage tape cartridge includes a housing having a reel within and rotatably supported by the housing. Two or more data storage tapes are wound up on the same rotary axis of the reel. Each subsequent winding of a first one of the tapes is separated from the previous winding of the first tape by at least another one of the other tapes. A leader pin is attached to a free end of each of the tapes. The leader pins may be connected to one another. The leader pins may be disconnected from one another as part of process for mounting the cartridge in a tape drive.
