A recording apparatus is provided. An adjustment unit executes adjustment processing for adjusting a delay amount of a timing signal. An input control unit executes input control to input continuously recording target data to be recorded to a storage medium, to a buffer memory. A recording control unit executes recording control for recording the recording target data held in the buffer memory to the storage medium, using an input/output unit configured to receive data from the storage medium according to the timing signal. A control unit performs control such that the input control is started before a recording start instruction and the recording control is started in response to the recording start instruction, and such that the adjustment processing is executed during execution of the input control and before the recording control is started in response to the recording start instruction.

A magnetic disk device includes a magnetic disk that includes a plurality of tracks, a magnetic head for reading data from the magnetic disk, and a controller. The controller begins controlling the magnetic head to move to a second track of the plurality of tracks from a first track of the plurality of tracks before decoding of a first track signal output from the magnetic head is completed, wherein the first track signal is output from the magnetic head while the magnetic head is positioned over the first track.

A system and method for improving the management of data input and output (I/O) operations for Shingled Magnetic Recording (SMR) devices in a network storage system is disclosed. The storage system includes a storage controller that receives a series of write requests for data blocks to be written to non-sequential addresses within a pool of SMR devices. The storage controller writes the data blocks from the series of write requests to a corresponding sequence of data clusters allocated within a first data cache of the storage controller for a thinly provisioned volume of the pool of SMR devices. Upon determining that a current utilization of the first data cache's data storage capacity exceeds a threshold, the sequence of data clusters including the data blocks from the first data cache are transferred to sequential physical addresses within the SMR devices.

Methods and systems for recording streaming audio and video by directing an incoming audio visual stream to a discrete memory region serving as a virtual display. The virtual display is configured with a section visible to the viewer and a section invisible to the viewer, wherein a streaming video is hidden from the user's display under all conditions. The user's browser is pre-loaded with hooks to redirect the video portion of the stream to the invisible section of the virtual memory wherein a video capture tool specifically designed to interact with the hooks can now recognize each function call, and intercept each frame as it is rendered in the GPU. Concurrently, the audio portion of the stream is remapped using an audio indexing application. The GPU framebuffers and audio sinks are multiplexed together and saved to disk. The file is immediately accessible for playback or copying.

An electronic apparatus and a controlling method thereof are provided. The electronic apparatus includes a buffer configured to store audio data of an audio stream; and a processor configured to decode the audio data stored in the buffer, wherein the processor is further configured to determine a reproducing time corresponding to the audio data stored in the buffer, compare the reproducing time and a predetermined reproducing time, and control a storage amount of the audio data in the buffer so that an amount of the audio data corresponding to the predetermined reproducing time can be maintained in the buffer.

A method for processing audio data includes: setting a first queue for managing at least one configured information control node of audio data to be played and a second queue for managing at least one configured information control node of played audio data, wherein each of the at least one configured information control node contains attribute information for the audio data to be played; unchaining a unit of the at least one configured information control node from the first queue; reading audio data to be played corresponding to the unit of the at least one configured information control node according to the attribute information for the audio data to be played in the unit of the at least one configured information control node; and chaining the unit of the at least one configured information control node to the second queue.

A method for dynamically changing a buffer threshold in a tape drive, according to another embodiment, includes monitoring a history of sizes of data transactions between sync commands, the data transactions being from a host to a tape drive, determining that a next sync command is expected to be received relatively sooner or relatively later based on the history of data size transactions, writing buffered data to a magnetic recording tape in response to determining that the next sync command will be received relatively sooner, and increasing a buffer threshold for delaying writing to the magnetic recording tape in response to determining that the next sync command will be received relatively later. A computer program product according to one embodiment includes a computer readable storage medium having program code embodied therewith, the program code readable/executable by a processor to perform the foregoing method.

A system on chip includes: a codec encoding image frames; and a codec controller sending the image frames to the codec and allocating a buffer for encoding the image frames, The codec controller sends a first image frame to the codec. The codec controller allocates the first buffer to a memory and sends the first image frame to the codec. The codec encodes the first image frame and sends the encoded first image frame to the codec controller. The codec controller allocates the first buffer to the memory and sends a second image frame to the codec. The codec requests the codec controller to allocate a second buffer of a second size. The codec controller allocates the second buffer to the memory and sends the second image frame to the codec, and the codec encodes the second image frame and sends the encoded second image frame to the codec controller.
