The present disclosure describes aspects of codeword interleaving over magnetic media surfaces. In some aspects, segments of a codeword are spread or interleaved across multiple surfaces of magnetic storage media. Data for one or more codewords may be received by a read/write channel and, for each codeword, a respective index is selected, received, or generated. The index may indicate which sector partitions of the multiple surfaces that segments of one of the codewords are to be written. The data of the codewords can be segmented and then arranged in an interleaver based on the respective index to which the codeword corresponds. The codeword segments are written from the interleaver to sectors of the multiple surfaces of the magnetic media. By so doing, codewords may be spread across multiple surfaces, such that a loss of a portion of a segment track does not prevent readback and decoding of the codewords.

Systems and methods are disclosed relating to electro-mechanical devices and related computer control and audio processing systems intended to optimize playback fidelity of phonograph records. Said recordings are manufactured by a process that employs a cutting head assembly driven in a straight path from the outer to the inner-most radius of the recordable surface. However, most record turntables device that are used to play back phonograph records rely on a stylus transducer attached to the end of a pivoting arm. Instead of the linear path followed by the original cutting head, said tonearm traces an arc across the surface of the recorded disk resulting in playback distortion proportional to error in alignment of said stylus relative to the tangent of the groove. This invention addresses this deficiency and produces an optimal audio quality of playback of phonograph records.

Disclosed herein are information capture systems and related methods. An information capture system includes a sensor secured to an object configured to be involved with a possible event. The sensor is configured to detect one or more stimuli that are associated with the possible event, and transmit a sensor signal indicating data corresponding to the one or more stimuli. The information capture system also includes a recording device configured to record information responsive to a triggering event determined from the sensor signal. A method includes analyzing sensor data from the sensor, determining, from the sensor data, that a triggering event occurred, and recording post-trigger information following the determination of the triggering event.

A hopscotch sound recording and playback system and method for a strip of motion picture film is presented herein. The system and method includes a sound recording assembly configured to record at least two soundtracks onto the strip of motion picture film, between film perforations, and in a laterally and longitudinally offset manner. The system and method also includes a sound playback assembly configured to read the at least two soundtracks by switching or hopscotching between the soundtracks to create an assembled soundtrack. The assembled soundtrack includes alternating sections from the two soundtracks disposed between the perforations on the film.
