Abstract: A system includes a system-on-a-chip integrated circuit and a preamplifier integrated circuit. The system-on-a-chip integrated circuit includes an interface configured to receive an analog sensor signal and a read/write channel configured to digitize the analog sensor signal. The preamplifier integrated circuit is communicatively coupled to the system-on-a-chip integrated circuit and is configured to amplify the analog sensor signal.

Abstract: A data storage library includes a number of storage cartridges arranged in a rack accessed by a actuated media player. The actuated media player is adapted to move along a plane relative to a fixed subset of the storage cartridges in the rack to and to selectively couple to each storage cartridge of the fixed subset to facilitate selective read/write access.

Abstract: Apparatus for data storage in a cartridge library archival system. In some embodiments, a plurality of portable data storage cartridges are provided. Each cartridge has a sealed housing which encloses at least one head-disc interface (HDI) with a magnetic data transducer adjacent a rotatable data recording medium. An access station has control electronics configured to transfer data signals between a memory and the transducer of a selected cartridge loaded to the access station. The access station further has an external voice coil motor (VCM) configured to engage and advance the transducer of the selected cartridge across a recording surface of the medium. A transport mechanism can be used to automatically load the cartridges to the access station. Multiple cartridges can be loaded sequentially or concurrently to support various data transfer operations.

Abstract: Systems and methods are disclosed to perform media certification with different recording widths, in accordance with certain embodiments of the present disclosure. An apparatus may be configured to record data using at least two selectable recording widths. In some embodiments, the recording width may be controlled by adjusting a laser current supplied to a laser emitter of a heat assisted magnetic recording (HAMR) device. Certification data may be recorded to a storage medium at a selected recording width, with wider widths reducing testing time and narrower widths reducing wear on write heads. In some embodiments, an apparatus may be configured to record servo data using a first recording width to a storage medium, and record certification data using a second recording width. The drive may record servo data and certification during a first disc rotation, and may record servo data and read certification data during a second disc rotation.

Abstract translation: 根据本公开的某些实施例，公开了系统和方法来执行具有不同记录宽度的媒体认证。 设备可以被配置为使用至少两个可选择的记录宽度来记录数据。 在一些实施例中，记录宽度可以通过调节提供给热辅助磁记录（HAMR）装置的激光发射器的激光电流来控制。 认证数据可以以选定的记录宽度被记录到存储介质，具有更宽的宽度，减少了测试时间和较窄的宽度，从而减小了写入头上的磨损。 在一些实施例中，装置可以被配置为使用第一记录宽度将伺服数据记录到存储介质，并且使用第二记录宽度记录认证数据。 驱动器可以在第一盘旋转期间记录伺服数据和认证，并且可以在第二盘旋转期间记录伺服数据和读取认证数据。
