Abstract

Abstract A magnetic disc recording and/or reproducing apparatus comprises a frame, a recording/reproducing unit detachably mounted on a frame and a front panel detachably mounted on the frame and having an inserting opening through which the magnetic disc is inserted and removed. The frame is primarily designed to accommodate a first recording/reproducing unit adapted for a first magnetic disc and is selectively mounted with either one of the first recording/reproducing unit and a second recording/reproducing unit adapted for a second magnetic disc having a smaller diameter. Depending on the selected recording/reproducing unit, either one of a first front panel for the first magnetic disc and a second front panel for a second magnetic disc is selectively mounted on the frame.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 325 words
A magnetic disc recording and/or reproducing apparatus for cooperation with an external information processing system for recording and/or reproduction of digital data on and from a flexible magnetic disc comprising: a frame having a size substantially identical to a standardized frame used in a first standardized magnetic recording and/or reproducing apparatus for accommodating a first recording/reproducing unit for recording and/or reproducing a digital data on and from a first standardized flexible magnetic disc having a first standardized diameter, said frame being adapted to be mounted on a body of the external information processing system in a detachable manner; a second recording/reproducing unit mounted on said frame for recording and/or reproducing a digital data on and from a second standardized flexible magnetic disc having a second standardized diameter smaller than the first standardized diameter, said second recording/reproducing unit having a second size substantially smaller than the size of the first recording/reproducing unit; a front panel closing a front end of the frame and having an inserting opening with a size so as to allow insertion of said second standardized flexible magnetic disc therethrough; and a connector mounted on a rear end of the second recording/reproducing unit, said connector having a design identical to a standardized connector used in the first standardized apparatus; and an intervening member connected to said rear end of the second record/reproducing unit, said intervening member having a size measured perpendicularly to the front panel such that an overall size of the second recording/reproducing unit and the intervening member connected to the second recording/reproducing unit becomes substantially identical to that of the first recording/reproducing unit when measured perpendicularly to the front panel, said intervening member carrying a socket corresponding to said connector at a first side making contact with the rear end of the second recording/reproducing unit and a second connector on a second side opposite to said first side, and electrically connecting the second recording/reproducing unit to the external information processing system.
