Title: Teruyuki Narita: Innovator in Magnetic Disk Technology

Introduction

Teruyuki Narita is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of magnetic disk technology, holding a total of 4 patents. His work focuses on enhancing the performance and reliability of storage apparatuses.

Latest Patents

One of Narita's latest patents is a storage apparatus designed to reduce read errors caused by thermal asperities in magneto-resistive heads. This invention includes a read demodulating unit that processes read data and servo data for head positioning. It features a thermal asperity fault detecting unit that sets a threshold for the reproduction waveform signal and generates a fault signal when this threshold is exceeded. The error avoiding unit then executes several corrective actions, such as increasing the cut-off frequency of a high pass filter and locking the automatic gain control.

Another notable patent is for a magnetic disk apparatus that can identify individual product specifications efficiently. This invention includes an identification circuit that determines performance specifications, such as the number of heads and disks. The circuit utilizes a resistor configuration and an A/D converter to convert voltage values into digital data, which is then compared against stored performance information to control the magnetic disk apparatus effectively.
