The Microline stylus almost exactly duplicates the shape of the cutting stylus
used to product the original master disc.
This enables it to track portions of the groove other styli cannot reach,
resulting in extremely accurate tracing of high frequency passages
and ruler-flat frequency response within the audible range.
The unique multi-level shape wears more evenly, allowing greatly extended
record and stylus life.
The sophisticated Linear Contact stylus provides a vertical contact area
several times that of the elliptical, enabling it to respond to delicate groove modulations.
The wide front radius distributes the stylus pressure more evenly,
reducing wear on both the stylus and record.
The Elliptical stylus has two radii, the front radius being wider than the side radius.
This allows the stylus to ride the center of the groove, like the conical,
while the smaller side radius can more accurately track higher frequencies.
Elliptical styli are available in several sizes
– such as 0.2 x 0.7 mil, 0.3 x 0.7 mil and 0.4 x 0.7 mil –
with the first number indicating the side radius.
The smaller the side radius, the better the sound quality can be.
The Conical stylus is the simplest, least expensive and most widely used stylus.
Its spherical tip, which has a typical radius of 0.7 mil, normally touches
the center of the record groove walls.
The conical design works best in moderate to lower priced, and older, record players
with higher tone arm tracking forces.
