Abstract: In accordance with one implementation, a method for mitigating cache transfer time entails reading data into memory from at least two consecutive elliptical data tracks in a main store region of data storage and writing the data read from the at least two consecutive elliptical data tracks to a spiral data track within a cache storage region.

Abstract: Apparatus and method for data security in a data storage device. In some embodiments, an alternating pattern is written to a magnetic recording medium as a sequence of symbols at a selected clock rate. A repeatable magnetic signature is generated by reading the alternating pattern from the medium, the magnetic signature having relatively weak entropy at boundaries of the symbols. A multi-bit digital sequence is extracted from the repeatable magnetic signature, the digital sequence having relatively strong entropy. The digital sequence is stored in a separate memory coupled to the medium. Access to data stored on the medium is authenticated responsive to the digital sequence stored in the separate memory.

Abstract: A data-storing method for accelerated read throughput of a channel received as part of a multi-channel data stream includes writing a first channel segment of the multi-channel data stream to a first continuous sequence of physical blocks along a first data track of a storage medium within a storage device and identifying a second channel segment of the multi-channel data stream as being a continuation of the first channel segment. The method further includes writing the second channel segment to a second continuous sequence of physical blocks along a second data track responsive to the identification, the second continuous sequence of physical blocks being offset from the first continuous sequence in a down-track direction by a minimum block offset, the minimum block offset representing at least a number of physical blocks on the storage medium that rotate below a read/write element of the storage device during a time that the read/write element is moved from the first data track to the second data track.

Abstract: The technology disclosed herein provides a system for generating a personal unclonable function (PUF) for a user based on a biometric data related to the user. Implementations of the system include a camera to generate a partial image of a user's tongue, a sensor to generate a moisture level in the user's saliva, a PUF generator configured to generate a PUF benchmark of the user based on combination of the partial image of a user's tongue and the moisture level in the user's saliva, and an access control unit configured to control access to one or more user devices based on the PUF benchmark.
