Latest Patents

Avraham Perahia holds a patent for a "High density bias linearized magnetic recording system utilizing Nyquist." This digital magnetic recording system employs partial response signaling to achieve the Nyquist data pulse rate while minimizing bandwidth. The introduction of A.C. bias linearizes the magnetic medium, allowing for reliable multilevel data storage without compromising data accessibility. The system utilizes Class IV partial response with sinusoidal lobes in the data frequency spectrum. The basic binary data is converted to ternary, which is then precoded and recorded on the magnetic medium through an interleaved dipulse sequence. A pilot tone is included at the spectral null for timing recovery and automatic gain control.
