A magnetic tape cartridge has a cartridge casing, a single reel around which a magnetic tape is wound and which is contained in the cartridge casing for rotation and a leader pin fixed to the leading end portion of the magnetic tape. The leader pin is provided at its opposite ends with engagement portions which are brought into engagement with a tape drawing mechanism of a recording and reproducing system when the magnetic tape cartridge is loaded in the recording and reproducing system. The end face of each engagement portion is provided with a recess at which the tape drawing mechanism chucks the leader pin.

1. Field of the Invention
This invention relates to a magnetic tape cartridge, and more particularly to a magnetic tape cartridge comprising a cartridge casing and a single reel around which a magnetic tape is wound and which is contained in the cartridge casing for rotation.
2. Description of the Related Art
FIG. 1 is a perspective view showing a magnetic tape cartridge in accordance with an embodiment of the present invention with the slide door closed,
FIG. 2 is a perspective view showing the magnetic tape cartridge with the slide door opened,
FIG. 3 is a side view partly cutaway showing a basic appearance of the leader pin,
In FIGS. 1 and 2, a magnetic tape cartridge in accordance with an embodiment of the present invention comprises a cartridge casing 1 formed by upper and lower casing halves 1a and 1b and a single reel (not shown) around which a magnetic tape is wound and which is supported for rotation in the cartridge casing 1. A tape outlet opening 2 through which the magnetic tape is drawn out is formed in one end face of the cartridge casing 1 near a corner thereof. A slide door 3 for opening and closing the tape outlet opening 2 is mounted in the cartridge casing 1 to be slidable back and forth between a closing position where it closes the tape outlet opening 2 and opening position where it opens the same. The slide door 3 is urged toward the closing position by a spring not shown disposed between a side face of the cartridge casing 1 and the slide door 3.
As shown in FIG. 2, a leader pin 4 fixed to the leading end of the magnetic tape is held inside the tape outlet opening 2. When the magnetic tape cartridge is loaded in a tape drive system, a reel drive means of the tape drive system is brought into engagement with engagement teeth (not shown) on the reel which is exposed in the bottom face of the cartridge casing 1 at the center thereof and a tape drawing mechanism of the tape drive system pushes the front end face 3a of the slide door 3 to open the slide door 3. Further the tape drawing mechanism chucks the leader pin 4 and pulls the leader pin 4 into the system, whereby the magnetic tape is set in the tape drive system so that data can be recorded on or read out from the magnetic tape.
A knob 5 for inhibiting erasure and write projects outside in one side face of the cartridge casing 1.
