High-density flexible disk drive having a function of facilitating correct insertion of a large-capacity flexible disk thereinto without an insertion error

Abstract

In a high-density flexible disk drive, a color of at least a surface of a cover ( 22 ) (in addition, a color of at least a surface of an eject button ( 30 )) is different from that of at least a surface of a body of a front panel ( 20 ). A user can visually distinguish the high-density flexible disk drive from a normal-density dedicated flexible disk drive in which a color of a surface of a cover is identical with that of a surface of a body of a front panel. Thus, a large-capacity flexible disk can be correctly inserted into the high-density flexible disk drive without being erroneously inserted into the normal-density dedicated flexible disk drive.

What is claimed is:  
     
         1 . A high-density dedicated flexible disk drive for insertion of a large-capacity flexible disk, said large-capacity flexible disk comprising a case containing a magnetic disk medium, said case having a notch formed on a forward side of said case in an insertion direction of inserting said large-capacity flexible disk into said high-density dedicated flexible disk drive, wherein said high-density dedicated flexible disk drive comprises a disk holder unit for holding said large-capacity flexible disk when it is inserted into said high-density dedicated flexible disk drive, said disk holder unit having a protrusion formed at a position corresponding to said notch of the large-capacity flexible disk held by said disk holder unit.  
     
     
         2 . A high-density/normal-density flexible disk drive for insertion of a large-capacity flexible disk, said large-capacity flexible disk comprising a case containing a magnetic disk medium, said case having a notch formed on a lateral side provided with a chamfered portion for preventing reverse insertion of said large-capacity flexible disk, said notch having a particular shape and formed at a particular position so that said notch is engaged by a reverse insertion preventing lever of a normal-density dedicated flexible disk drive, wherein said high-density/normal-density flexible disk drive comprises a disk holder unit for holding said large-capacity flexible disk when it is inserted into said high-density/normal-density flexible disk drive, said disk holder unit having a recess formed at a position corresponding to said notch and extending in a direction perpendicular to an insertion direction of inserting said large-capacity flexible disk, and a reverse insertion preventing lever formed at said recess to be movable in an escaping direction of escaping from said recess upon collision by said chamfered portion.
