A voice recording device that connects/is connected to a network, comprising a voice recording circuit that acquires voice and records the acquired voice as a voice file, a transmission circuit that transmits the voice file to a network, and a control circuit, the control circuit including an information extraction section that extracts associated information that has been associated with the voice file, and a display that displays the associated information associated with a voice data file.

According to one embodiment, a magnetic disk device includes a disk including two first servo sectors and at least a second servo sector, a head, and a controller, wherein the first servo sector includes burst data and a first data pattern written before the circumferential direction of the burst data, the second servo sector includes the burst data, the first data pattern, and a second data pattern written after the circumferential direction of the burst data, a first frequency of the first data pattern is different from a second frequency of the second data pattern, and a first length of the first data pattern is different from a second length of the second data pattern.

Example methods and apparatus to audio watermarking and watermark detection and extraction are disclosed herein. An example apparatus disclosed herein includes memory, computer readable instructions, and processor circuitry to execute the computer readable instructions to at least detect a first symbol, a second symbol, a third symbol, and a fourth symbol sequentially in encoded audio samples, determine whether the first symbol is a synchronization symbol, in response to a determination that the first symbol is a synchronization symbol, determine that the first symbol and the third symbol are associated with a first message and the second symbol and the fourth symbol are associated with a second message, and output at least one of the first message or the second message.

A system includes a recorder configured to record audio and/or video of a subject of interest and output a recording of the subject of interest and a non-contact sensor associated with the recorder. The non-contact sensor is constructed and arranged to measure movement and/or vibration of the subject of interest from substantially the same perspective and at the same time as the recorder. The system includes a controller configured to transform the measured movement and/or vibration of the subject of interest measured by the non-contact sensor into a tactile data stream for sending to a haptic display device for playback with the recording of the subject of interest by the recorder and providing haptic effects corresponding to the measured movement and/or vibration to a user of the haptic display device in synchronization with the recording.

Systems and methods are disclosed for magnetoresistive asymmetry (MRA) compensation using a digital compensation scheme. In certain embodiments, a method may comprise receiving an analog signal at a continuous-time front end (CTFE) circuit, and performing analog offset compensation to constrain an extremum of the analog signal to adjust a dynamic range based on an input range of an analog-to-digital converter (ADC), rather than to modify the analog signal to have a zero mean. The method may further comprise converting the analog signal to a digital sample sequence via the ADC; performing, via a digital MRA compensation circuit, digital MRA compensation on the digital sample sequence; receiving, via a digital backend (DBE) subsystem, the digital sample sequence prior to digital MRA compensation; and generating, via a DBE, a bit sequence corresponding to the analog signal based on an output of the DBE subsystem and an output of the digital MRA compensation circuit.

The technology disclosed herein pertains to a system and method for managing write failures in a disc drive. Implementations disclosed herein provide a method including monitoring write fault events per sector for a storage device, in response to a write fault event, updating a write fault repeat count table, wherein the repeat count table tracks a number of write fault repeat counts per sector, comparing a write fault repeat count for a sector to a predetermined threshold write fault repeat count, and in response to determining that the write fault repeat count for a sector is above the predetermined threshold write fault repeat count, performing a write-reassign operation.

An apparatus, method and computer program, the apparatus comprising: processing circuitry; and memory circuitry including computer program code, the memory circuitry and the computer program code configured to, with the processing circuitry, enable the apparatus to: enable a wireless connection to be established with an electronic device; capture an audio signal and enable the captured audio signal to be sent to the electronic device using the wireless connection to enable the captured audio signal to be used to create an enhanced audio signal; and wherein the apparatus is arranged to be removeably attachable to the electronic device.

This invention is directed to a computerized audio content gifting device. The ability to send audio content to a recipient as a gift allows the personalization of gifts such as flowers and candy to be made. The invention includes a housing with a circuit board, operational buttons, a communication port, a speaker, an attachment member, and a set of computer readable instructions stored on the computer readable medium that, when executed by the processor, provides for: receiving audio content from a server in electronic communications with the circuit board using the communications port, playing the audio content when an operational button is placed in the “on” position. The invention can also determine if there are copyright restrictions on the audio content and manage the number of authorized copies.
