A common-source common-gate (CS-CG) differential amplifier is coupled to the read element through a transmission line having a transmission line impedance Z | 2022-05-26 |
20220165300 | WRITER WITH ADAPTIVE SIDE GAP - A PMR (perpendicular magnetic recording) write head configured for thermally assisted magnetic recording (TAMR) and microwave assisted magnetic recording (MAMR) is made adaptive to writing at different frequencies by inserting thin layers of magnetic material into the material filling the side gaps (SG) between the magnetic pole (MP) and the side shields (SS). At high frequencies, the thin magnetic layers saturate and lower the magnetic potential of the bulky side shields | 2022-05-26 |
20220165301 | MAGNETIC RECORDING MEDIUM, TAPE CARTRIDGE, AND DATA PROCESSING METHOD - To provide a magnetic recording medium that has excellent traveling stability in spite of having a thin total thickness and a thin thickness of an underlayer, and is suitable for use in a recording/reproducing device for adjusting the width of the magnetic recording medium by adjusting a tension of the magnetic recording medium in a longitudinal direction thereof. | 2022-05-26 |
20220165302 | MAGNETIC RECORDING MEDIUM - An object is to provide a magnetic recording medium having excellent traveling stability and a thin total thickness. | 2022-05-26 |
