Problems solved by technology

Therefore, during reeling, the tape 316 may be caught and damaged by nearby parts, or oil or grease applied to nearby parts may be deposited on the tape 316, which does not guarantee a safe rewinding operation.
[0018] Second, consider the following situation: During reproduction, an abnormality occurs in the S reel base 301 on the tape supply side, so that the magnetic tape 316 cannot be supplied, and not only the S reel base 301 stops rotating, but also the T reel base 302 stops rotating.
[0022] As mentioned above, during normal exception removal operations, tape damage may occur during cartridge ejection, and safe ejection of the cartridge cannot be guaranteed

Embodiment Construction

[0077] The invention will be described below by way of example with reference to the accompanying drawings.

[0078] FIG. 1 is a plan view of a magnetic recording / reproducing apparatus 100 in an unloaded mode in which a magnetic tape cassette can be inserted / extracted, according to an embodiment of the present invention. In FIG. 1, some components are omitted for simplicity.

[0079] The magnetic tape 2 is wound on two reels (not shown), which are placed in the cassette 1 . In FIG. 1, only the outline of the tape cassette 1 is shown (by a single-dotted line) and only the portion of the magnetic tape 2 extending outside the tape cassette 1 is shown (by a single-dotted line) for easy viewing. The tape cartridge 1 is placed on a sub-chassis 3 . An S reel base 4 and a T reel base 5 are rotatably mounted on the auxiliary reel frame 3 and cooperate with two tape reels (not shown) in the tape cassette 1 .

[0080] An idler gear 6 is swingably mounted to a central gear shaft 9 exte...

Abstract

The magnetic recording / reproduction apparatus of this invention records / reproduces information on / from a magnetic tape. The apparatus includes: a capstan shaft; a pinch roller; a supply reel base; a winding reel base; a reel driving source; and abnormality detection means, wherein in response to the detection of the abnormality by the abnormality detection means, the reel driving source performs an abnormality relief operation including rotating one of the winding reel base and the supply reel base in a direction of winding the magnetic tape by a predetermined amount and then rotating the other of the winding reel base and the supply reel base in a direction of winding the magnetic tape by a predetermined amount.

Description

technical field [0001] The present invention relates to a magnetic recording / reproducing apparatus which can be used as a video tape recorder (VTR). Background technique [0002] In recent years, magnetic recording / reproducing apparatuses such as VTRs tend to use ultra-thin magnetic tapes as recording media in accordance with the digitization of data and the need for long-time recording / reproducing. [0003] Such an ultra-thin magnetic tape is subjected to an operation performed by a mechanism of the magnetic recording / reproducing apparatus: the ultra-thin magnetic tape is pulled out from a cassette, and is loaded to be transported around a predetermined portion of the periphery of the rotary head cylinder. In this manner, while moving, the magnetic tape is kept in contact with the magnetic head provided on the rotary head cylinder, thereby enabling recording / reproduction of information on the magnetic tape. The tape is then rewound on a reel in the cassette, and the casset...
