An active matrix substrate includes: storage capacitor line extended sections 118ax, 118qx, etc. The STO oscillation layer has a large angle magnetization oscillation frequency that is locked to a magnetic medium bit resonance frequency f0 when the rf current has a frequency f=f0 and a threshold current density is applied. The driving coupler may be provided with a plurality of driving tips. The elongated angled bracket defines first and second sidewalls with an interior angle there-between. The multiple layer multileaf collimator is not limited to a single type of multileaf collimator and thus is suitable for use in a variety of multileaf collimator designs, including single focus and double focus multileaf collimators. A disc drive that records data on a recording medium having a management area and data area records the support information in the management area.
