Abstract: Systems and methods are disclosed for providing secure access to a data storage device. A user may provide tap inputs, such as taps or knocks, on an enclosure of the data storage device. The data storage device may determine whether the tap inputs are valid and may allow access to the data storage device (e.g., to non-volatile memory of the data storage device) when the tap inputs are valid.

Abstract: A tape embedded drive can include tape media for storing data, a first tape reel and a second tape reel, each coupled to one end of the tape media, and a head stack assembly (HSA). The HSA can include a first head assembly having at least one read head and one write head and a second head assembly having a non-operable head incapable of reading or writing. In an embodiment, the first head assembly is configured to be placed along a first side of the tape media and the second head assembly with the non-operable head is configured to be placed along a second side of the tape media opposite the first side of the tape media.

Abstract: Systems and methods are disclosed for providing secure access to a data storage device. A user may move the data storage device (e.g., wave, twist, etc.). The data storage device may determine whether the motions valid and may allow access to the data storage device (e.g., to non-volatile memory of the data storage device) when the motions are valid.

Abstract: A storage system can include a first tape storage drive (TSD), a second TSD, and a printed circuit board assembly (PCBA) where the first and second TSD are coupled back-to-back, with the PCBA between the two. The first TSD can include a first enclosure, a first head assembly, a first actuator, and a first connector. The second TSD can include a second enclosure, a second head assembly, a second actuator, and a second connector. The PCBA can include a first side having a first mating connector configured to connect to the first connector for the first TSD, a second side opposite the first side, the second side having a second mating connector configured to connect to the second connector for the second TSD, and a controller configured to control activation of the first actuator of the first TSD and the second actuator of the second TSD.

Abstract: An adapter or Data Storage Device (DSD) communicates with a Single Board Computer (SBC). SBC interface circuitry of the adapter or DSD is configured to provide power to the SBC and to send data to and receive data from the SBC. In the case of an adapter, an SBC connector of the SBC interface circuitry is configured to physically contact the SBC when the SBC is connected to the adapter through the SBC connector.
