Abstract
A magnetic recording and reproducing apparatus and a method for braking a reel assembly comprising a lower disc rotatably supported by a stationary shaft located on the deck and an upper disc arranged on the stationary shaft to rotatably coupled to an upper portion of the lower disc. Thus, the upper and lower discs are rotatably coupled to a tape reel of a tape cassette. A disc gear is positioned between the upper and lower discs to receive power from a capstan motor. A friction member is disposed between and in contact with the lower disc.
Claims11
A magnetic recording and reproducing apparatus rotatably installed on a deck to drive a tape reel of a tape cassette, comprising:
- a reel assembly coupled to the tape reel;
- and
- wherein the reel assembly is configured to contact with the deck to generate a predetermined frictional force during rotation so that rapid rotation of the reel assembly is prevented.
A magnetic recording and reproducing apparatus having a reel assembly rotatably installed on a deck to drive a tape reel of a tape cassette, comprising:
- a lower disc rotatably supported by a stationary shaft located on the deck;
- an upper disc arranged on the stationary shaft and rotatably coupled to an upper portion of the lower disc so that each disk rotates together, the upper disc being coupled to the tape reel of the tape cassette;
- a disc gear positioned between the upper and lower discs to receive power from a capstan motor, the disc gear is rotatably positioned on the deck;
- and
- wherein the reel assembly is configured to contact with the deck to generate a predetermined frictional force during rotation so that rapid rotation of the reel assembly is prevented.
A method for braking a reel assembly of a magnetic recording and reproducing apparatus for preventing a magnetic tape of a tape cassette mounted on the reel assembly from being unwound when the magnetic tape is loaded, the reel assembly comprising a lower disc rotatably installed on a deck and an upper disc coupled to an upper portion of the lower disc to rotate together with the lower disc, the upper disc coupled to a tape reel of the tape cassette, the method comprising the steps of:
- withdrawing and transferring the magnetic tape;
- rotating the reel assembly due to the transferring of the magnetic tape;
- and
- braking the reel assembly simultaneously with the rotation of the reel assembly, and
- wherein the reel assembly brakes by an internal friction force generated during the rotation of the reel assembly.
