Claim 13, which is representative for our purposes,
follows:
13. A magnetic head mechanism used for a miniaturized
magnetic disk apparatus, a lower and an upper magnetic head
being provided in said magnetic head mechanism, said upper
magnetic head being provided on a head arm being rotatably
supported with respect to a head carriage and making contact
with the upper surface of a flexible magnetic disk, said lower
magnetic head being provided on a head carriage and making
contact with the lower surface of said flexible magnetic disk,
said two magnetic heads opposing each other with said flexible
magnetic disk therebetween, said magnetic head mechanism
comprising:
said upper magnetic head being provided on said head arm
rotatably supported with respect to said head carriage, having
a first slider which slides on the upper surface of said
flexible magnetic disk, and
a first head core, integrally formed with said first
slider, to perform recording/reproducing of information
on/from said flexible magnetic disk,
said first slider having a groove with a width from 0.2mm
to 0.4mm, formed on a sliding surface of said first slider,
said groove extending in a tangential direction of the
rotation of said flexible magnetic disk and lying from one
side face of said first slider to the other side face of said
first slider; and
said lower magnetic head being fixedly mounted on said
head carriage, having
a second slider, which slides on the lower surface of
said flexible magnetic disk, having a planar sliding surface,
without a groove being formed on the sliding surface of said
