Abstract: PROBLEM TO BE SOLVED: To obtain the modulation circuit in which leakage of a carrier caused by a difference of a DC component from base band I, Q signals received by an orthogonal modulator is prevented. SOLUTION: Reference adjustment circuits 3, 4 use respectively low pass filters 3d, 4d to extract DC components DC1, DC2 for base band I, Q signals. The DC components DC1, DC2 are stored in an I DC component storage memory 7 and a Q DC component storage memory 8 respectively. Furthermore, a reference voltage Vref is stored in a reference voltage storage memory 10. A comparator 11 compares the DC components DC1, DC2 of the base band I, Q signals stored in the memories with the reference voltage Vref. An arithmetic circuit 12 generates an adjustment voltage AV to make the components DC1, DC2 of the base band I, Q signals in matching with the reference voltage Vref based on the result of comparison by the comparator 11 and gives it to the reference adjustment circuits 3, 4.

Title: Magnetic head for magnetic disk
Inventor: SATO YOSHIAKI
IPC: G11B5/60
Filed: 1998-10-09
Abstract: PROBLEM TO BE SOLVED: To improve a modulation characteristic by increasing a contact area with a magnetic disk without changing an external size to prevent head squeaking. SOLUTION: This magnetic head is provided with two recessed air grooves 5 roughly in the center part on a slider 2. Each air groove 5 rectifies the flow of air by the rotation of a floppy disk to improve a contact state with a magnetic disk. Since the two air groove 5 are narrower than a conventional air groove and provided on the slider, the contact area of the slider 2 with the floppy disk can be increased by the slider 2. Thus, for the magnetic head, only by changing the widths of the air grooves, the head squeaking and the modulation characteristic are easily improved.
