摘要： A digital information transmitting apparatus includes a first bit-compressor for bit-compressing a digital video information by a system of discrete cosine transform and a second bit-compressor for bit-compressing a digital audio information by a different system from the system of the first bit-compressor. A parity signal adder is provided for adding a parity signal to the bit-compressed digital video information from the first bit-compressor and the bit-compressed digital audio information from the second bit-compressor, in order to correct an error which occurs in a transmission path. A modulator is provided for phase-modulating the bit-compressed digital video information and the bit-compressed audio information, to which the parity signal has been added by the parity signal adder, and a transmitter ig provided for transmitting the modulated and parity signal added bit-compressed digital video information and bit-compressed digital audio information from the modulator, to the transmission path.

摘要： An apparatus and a method of recording and reading data to and from a multi-track magnetic tape utilize a multi-transducer magnetic head that is able to change its azimuth angle relative to the magnetic tape to compensate for variations in tape width due to sources of dimensional instability, such as age-related tape shrinkage. In one embodiment, the magnetic head contains at least eight write/read pairs positioned between two servo readers. Each servo reader includes a servo read transducer. During the original recording operation, the magnetic head is positioned at a write azimuth angle, for example, twenty degrees, such that a small change in the azimuth angle can compensate for age-related tape shrinkage. A read operation includes aligning two servo read transducers to two recorded servo tracks by laterally moving the magnetic head and changing the azimuth angle of the magnetic head to a read azimuth angle. In the preferred embodiment, the lateral movement of the head aligns the top servo read transducer to a desired servo track. Then, the magnetic head is pivoted about the top servo read transducer until the bottom servo read transducer is aligned to an adjacent servo track. The re-recording operation includes recording new data into the recorded tracks using the magnetic head that is positioned at the read azimuth angle.

摘要： A magnetoresistive (MR) head of a hard disk drive provides a readback signal from a data storage disk. The readback signal is high pass filtered, amplified, sampled and digitized to obtain a digital readback signal. A thermal component of the digital readback signal is removed from the digital readback signal by an efficient nonlinear process in which an envelope of the digital readback signal is estimated to obtain upper and lower envelope sequences. The upper and lower envelope sequences are averaged to derive the estimated thermal component to be subtracted from the digital readback signal.

摘要： A plurality of digital signals having total data rates of n bit/s or less are input to a digital recording device recording digital signals having a data rate of n bit/s. The digital signals are subjected to format-conversion for the digital recording device to be recorded therein. Furthermore, signals having a data rate of n/i1 bit/s or less are subjected to format-conversion to be recorded i1 times in the digital recording device. In the case where the data rate of the digital signals to be input is n/j bit/s, the digital signals are subjected to format-conversion so that the amount of data capable of being recorded per unit time is decreased by i/j; thus, the digital signals are recorded for a long period of time under the condition that the data recording time is prolonged j times. Furthermore, when input data to be recorded on a magnetic tape at a normal data rate by using a magnetic head mounted on a rotary cylinder is recorded, the recording device of the present invention makes it possible to select a plurality of types of track angles generated by the rotation number of the cylinder, the tape traveling speed, and the like.

摘要： A method and apparatus for recording an information on magnetic recording tracks, called camera tracks, formed on a photographic negative film while relative movement is caused between the photographic negative film and a magnetic head. When the magnetic head is located in an information recording region of the camera tracks, a signal of the information representing photographing conditions of each image frame such as the aspect ratio of each frame, exposure amount at the time of photographing, information on a light source, etc., is output to the magnetic head via a modulator and a recording current amplifier. When the magnetic head is located in an non-recording region of the camera tracks, direct current having a magnitude substantially equal to the optimal recording current of the magnetic head or alternating current having the frequency which is not less than 5 times the frequency of the signal is output to the magnetic head via the modulator and the recording current amplifier.

The reader comprises a field generating device the magnetic field produced by which defines an interrogation zone, wherein said field generating device comprises: (a) means for generating a magnetic field: (b) a transmit coil for transmitting an interrogating electromagnetic signal into the interrogation zone so as to interact with a magnetic tag, when present in said interrogation zone; and (c) at least one receive coil for receiving an electromagnetic signal generated by a tag in response to said interrogating signal and the magnetic field produced by said magnetic field generating means. The field generating means can take the form of a pair of hollow cylinders, giving rise to a “loop” reader, or it can be a flat magnet, giving rise to a “side pass” reader.
