Abstract
Abstract The cassette in a magnetic disc recording system is supported on a three point support having two locator points and one support pad, any or all of which may be adjustable. The locator points are received in corresponding openings in the cassette, and the cassette is supported thereon and on the pad to locate the cassette precisely in a predetermined position within the disc recording system.

Claim 1
Independent Claim
218 words
In a magnetic recording system including a support panel, a drive hub mounted in the support panel, means for rotating the drive hub, a magnetic transducer movably mounted in spaced relation to the drive hub and movable to selected positions along a path toward and away from the drive hub, a recording disc having at least one magnetizable surface, a cassette surrounding the disc and having an elongated opening therein adjacent the magnetizable surface and aligned with the path of movement of the transducer providing access for the transducer to the surface, a driven hub attached to the disc and accessible adjacent the surface of the cassette to the drive hub, the improvement comprising: locating means including a plurality of support points on the support panel and corresponding receiving means on the cassette, the cassette resting upon and being located by said support points and receiving means to locate and support the cassette in a predetermined position on the support panel to align the drive hub with the driven hub and to align the elongated opening with the transducer, and a carriage movable between a loading position and an operating position and constructed to hold the cassette, said carriage having openings to allow said support points to pass into the carriage to support and locate the cassette thereon.

In a magnetic recording system including a support panel, a drive hub mounted in the support panel, means for rotating the drive hub, a magnetic transducer movably mounted in spaced relation to the drive hub and movable to selected positions along a path toward and away from the drive hub, a recording disc having at least one magnetizable surface, a cassette surrounding the disc and having an elongated opening therein adjacent the magnetizable surface and aligned with the path of movement of the transducer providing access for the transducer to the surface, a driven hub attached to the disc and accessible adjacent the surface of the cassette to the drive hub, the improvement comprising: locating means including a plurality of support points on the support panel and corresponding receiving means on the cassette, the cassette resting upon and being located by said support points and receiving means to locate and support the cassette in a predetermined position on the support panel to align the drive hub with the driven hub and to align the elongated opening with the transducer, and a carriage movable between a loading position and an operating position and constructed to hold the cassette, said carriage having openings to allow said support points to pass into the carriage to support and locate the cassette thereon.
Claim 3
Dependent Claim
43 words
A magnetic recording system as defined in claim 1 wherein said locating means is vertically adjustable and includes at least two locator points received in corresponding receiving openings in the cassette to locate the cassette in said predetermined position on the support panel.
Claim 4
Dependent Claim
224 words
In a magnetic recording system including a support panel, a drive hub mounted in the support panel, means for rotating the drive hub, a magnetic transducer movably mounted in spaced relation to the drive hub and movable to selected positions along a path toward and away from the drive hub, a recording disc having at least one magnetizable surface, a cassette surrounding the disc and having an elongated opening therein adjacent the magnetizable surface and aligned with the path of movement of the transducer providing access for the transducer to the surface, a driven hub attached to the disc and accessible adjacent the surface of the cassette to the drive hub, the improvement comprising: a. first locator point means, b. second locator point means; c. first and second threaded means mounting said locator points on the support panel for vertical adjustment with respect to the support panel in response to rotation on said threaded means, d. locator pad means, e. third threaded means mounting said locator pad on the support panel for vertical adjustment with respect thereto in response to rotation on said third threaded means, and f. first and second openings in the cassette for receiving said first and second locator points to support the cassette thereon and on said pad to locate the cassette in a predetermined position on the support panel.
