Abstract
A magnetic tape cartridge has a single reel including a circular lower flange and a circular upper flange, a magnetic tape which is wound between the upper flange and the lower flange and a cartridge case including a lower case and an upper case. The upper flange closes a circular second opening of the upper case to form a central portion on an upper side of the cartridge case. It has become possible to provide a magnetic tape cartridge that has a reduced total thickness and is also advantageous in terms of costs. A magnetic tape cartridge can be also realized which is unlikely to be damaged even if it is subjected to careless handling.

A magnetic tape cartridge comprising:
- a single reel including a circular lower flange in which an engaging portion for engaging a rotary shaft of a recording/reproducing apparatus is centered, and a circular upper flange which is arranged so as to be opposed to the lower flange and has an outer diameter larger than the outer diameter of the lower flange;
- a magnetic tape which is wound between said upper flange and said lower flange;
- and
- a cartridge case within which said single reel is rotatably accommodated and which includes a lower case into which said rotation shaft is inserted and which has a first opening at a position corresponding to the engaging portion of said lower flange, and an upper case which has a circular second opening having an inner diameter larger than the outer diameter of said lower flange but smaller than the outer diameter of said upper flange;
- wherein said upper flange closes the circular second opening of said upper case to form a central portion on an upper side of said cartridge case.
A magnetic tape cartridge comprising a generally rectangular cartridge case in which a single reel wound with a magnetic tape is rotatably housed,
- wherein a magnetic tape drawing-out port, which becomes a passage for drawing out said magnetic tape from said cartridge case and rewinding said magnetic tape into said cartridge case, is provided on a side surface of said cartridge case at a position apart from a corner of said cartridge case.
