Abstract

PROBLEM TO BE SOLVED: To improve an operability by setting a common mediumsetting mechanism, a head and a head feed mechanism part for each medium and a detecting part for detecting the presence/absence of a cartridge and setting a record/reproduction mode. SOLUTION: At tape cartridge 27 has a common external form with a disk cartridge. When the tape cartridge is inserted from a common medium insertion opening 8, the cartridge is arranged to a predetermined record reproduction position by a medium- setting mechanism. Upon detecting that a medium is the tape cartridge 27, a medium- detecting mechanism sets an operation mode for a magnetic recording/reproducing apparatus 1 to a magnetic tape mode. A magnetic head 4 moves to a position where recording/reproduction is carried out to a magnetic tape 11. A medium-driving mechanism starts up and a driving pin 6a engages with a driving wheel 15 thereby rotating a driving shaft 14. A driving belt 18 comes in touch with an outer face of the magnetic tape 11 wound to reels 12, 13 thereby running the magnetic tape 11. A running system for the magnetic tape 11 is all set inside the tape cartridge 27 without projecting to the outside.

Incidentally, by reversing the rotation direction of the medium drive mechanism (not shown) of the magnetic recording / reproducing apparatus 1, the magnetic tape 11
Can be reversed. The end of the magnetic tape 1 can be detected by making the tape at the end of the magnetic tape 11 transparent. For example, magnetic tape 1
It is sufficient to use a general transmission type light detection mechanism that emits light from one side and detects light on the other side with 1 interposed therebetween. When recording or reproducing information on or from the magnetic tape 11, the magnetic recording / reproducing apparatus 1 controls the magnetic head 4 based on track position information provided in advance on the magnetic tape 11.
A servo mechanism (not shown) for performing servo control so as to follow one recording track (not shown) is provided. In this case, the track position information may be a sector servo signal that is common in a hard magnetic disk device, or a CD.
-A device using a groove for light reflection that is common in a ROM device may be used.

According to the magnetic recording / reproducing apparatus 1 of the first embodiment, both the disk cartridge and the tape cartridge can be used and the tape cartridge 27 can be used.
Does not protrude outside the magnetic recording / reproducing device 1,
Operability of the tape cartridge 27 is good. Further, the tape cartridge 27 can feed the magnetic tape 11 with a drive shaft engaged with the drive pin 6a of the medium drive mechanism of the magnetic recording / reproducing apparatus 1, so that the structure of the tape cartridge 27 is simple and inexpensive. In addition, tape cartridge 2
7 has a structure in which the first and second openings 23 and 24 can be opened and closed by the same shutter 25, so that the cost can be reduced. Also,
Since the magnetic recording / reproducing apparatus 1 drives the head feed mechanism 5 to contact the magnetic head 4 with the magnetic tape 11 after the medium cartridge 10 mounted by the medium detection mechanism 7 is confirmed to be the tape cartridge 27, Malfunction can be prevented and reliability can be improved.
