Chapter 7, Problem 19RETC
Explanation of Solution
Physical components of a disk drive:
Some of the components of rigid disk drive are as follows:
- Disk platters
- Actuator arm
- Spindle
- Read/ write head
Disk platters:
- Fixed disks have a control circuitry and some glass or metal disks called platters. It is bonded with a thin film of magnetizable material. The disk platters are stacked on a spindle that is turned on using a motor.
- The disk platter contains various concentric circles called as tracks. Mostly each and every track on the system contains the same number of sectors.
Actuator arm:
- The read/ write head are usually mounted on a rotating arm named as actuator arm.
- The axis of each actuator arm is enclosed by a coil which is induced with magnetic field...

I need help fixing the minor issue where the text isn't in the proper place, and to ensure that the frequency cutoff is at the right place.
My code:
% Define frequency range for the plot
f = logspace(1, 5, 500); % Frequency range from 10 Hz to 100 kHz
w = 2 * pi * f; % Angular frequency
% Parameters for the filters - let's adjust these to get more reasonable cutoffs
R = 1e3; % Resistance in ohms (1 kΩ)
C = 1e-6; % Capacitance in farads (1 μF)
% For bandpass, we need appropriate L value for desired cutoffs
L = 0.1; % Inductance in henries - adjusted for better bandpass response
% Calculate cutoff frequencies first to verify they're in desired range
f_cutoff_RC = 1 / (2 * pi * R * C);
f_resonance = 1 / (2 * pi * sqrt(L * C));
