    摘要: A system, device, and method for recording audio with the character and sonic benefits of a genuine analog recording is disclosed. More specifically, an electro-mechanical-software controlled closed loop analog signal processor (“CLASP”) system which is comprised of a CLASP unit containing firmware, a latency detection module, and CLASP hardware display and controls. The CLASP system further comprises CLASP software operably running on a digital audio workstation (“DAW”) which is also in operable communication with the CLASP unit. The CLASP unit is also in operable communication with an analog recordable medium. An analog audio signal is recorded on the analog recordable medium, which may consist of a coated tape, cup, cylinder, drum, or disk, and then immediately played back and routed to the DAW via an analog to digital converter, thus providing for digitally recorded analog audio. The CLASP system may also include converters and a mixing console.

    摘要: A cassette recorder amplifier system with a two stage preamplifier having direct current forward feed from the first to the second stage and direct current feedback from the second to the first stage to cause the second stage to operate without overloading as an input stage. The power amplifier has high direct current feedback and lower alternating current feedback for better linearity and more gain. Switch circuits and extra input terminals provide for recording on recording, aural monitoring of recording, and higher speed on fast forward and reverse.

    摘要: There is described a recording amplifier circuit for a magnetic recorder providing a very low output impedance in series with the winding on the magnetic recording head. The low output impedance is achieved by negative feedback, preferably derived from the voltage across the drive coil or derived from a separate coil on the magnetic head wound concentrically with the drive coil.

    摘要: Example preamplifier circuits, data storage devices, and methods to provide a preamplifier circuit with separate read and write power channels are described. The preamplifier circuit may include a write driver circuit configured to send a write signal to a writer element of a data storage device and a read driver circuit configured to receive a read signal from a reader element of the data storage device. The write driver circuit may receive a write power signal through a write power channel of a bus interface and the read driver circuit may receive a read power signal through a read power channel of the bus interface, where the write power signal and the read power signal are different. In some configurations, the different read and write power signals may be received from a switching regulator on the printed circuit board that mounts other data storage device electronics, such as the drive controller circuit and/or read/write channel circuit.
