load bearing upon the surface of the disk, the smaller the
frictional wear on both the sliding contact and the disk. If
the rigidity of the spring is increased, vibration is reduced
but if the weight of the load or the rigidity is increased,
there is more friction and greater wear on both the slider
head and the disk. Thus, there are various parameters to take
into account when designing a sliding contact-type magnetic
disk. The instant invention is said to achieve better results
than conventional devices by limiting the spring length to
less than 5mm and, preferably, to 1-3mm range, keeping the
magnetic head slider mass greater than 2mg, and urging the
head slider against the magnetic disk by a load of less than
1g inclusive.
Representative independent claim 1 is reproduced as
follows:
1. A contact type magnetic disk drive comprising:
a contact pad carrying an electromagnetic transducer for
recording and reproduction on an end thereof, and capable of
sliding in contact with a magnetic disk medium;
a magnetic head slider on which said contact pad is
mounted;
a suspension spring supporting said magnetic head slider;
and
