- means for winding said magnetic tape on said rotary drum;
- means for traveling said magnetic tape;
- wherein at least one of light emission intervals and light extinction intervals during a period from a time before said means for winding starts to wind said magnetic tape on said rotary head till said means for winding has finished winding is different from at least one of light emission intervals and light extinction intervals when said tape runs or travels after said magnetic tape is wound on the rotary drum.
- 2. A magnetic recording and reproducing apparatus for use with a magnetic tape having a light transmittable area on an end of said magnetic tape, comprising:
- light emitting means for emitting a light to illuminate said magnetic tape;
- means for sensing a light emission of said light emitting means to recognize a tape end when a tape taken-up position is said tape end;
- means for controlling light emission/extinction of said light emitting means;
- a rotary drum having a magnetic head mounted thereon:
- means for winding said magnetic tape onto said rotary drum;
- means for traveling said magnetic tape;
- means for taking-up said magnetic tape;
- means for supplying said magnetic tape;
- wherein at least one of light emission intervals and light extinction intervals of said light emitting means when at least one of said tape taking-up means and said tape supplying means is deviated from an associated one of respective predetermined revolution speeds which vary in accordance with current tape taken-up position, are different from at least one of light emission intervals and light extinction intervals of said light emitting means when both said tape taldng-up means and tape supplying means are at the respective predetermined revolution speeds at current tape taken-up position.
- 3. The apparatus of claim 2, wherein said respective predetermined revolution speeds at current tape taken-up position are respective revolution speeds of said tape taking-up means and said tape supplying means at current taken-up position at a recording tape speed or at a substantially the same tape speed as the recording tape speed.
- 4. A magnetic recording and reproducing apparatus for use with a magnetic tape having a light transmittable area on an end of said magnetic tape, comprising:
- a light emitter emitting a light through said magnetic tape;
- a light receiver sensing a light emission from said light emitting means to recognize the end of said magnetic tape when a taken-up position of said magnetic tape is the end of said tape;
- a light controller controlling light emission/extinction of said light emitter;
- a head drum having a rotary head mounted thereon:
- a winder winding said magnetic tape on said rotary drum;
- a tape driver for traveling said magnetic tape;
- wherein at least one of light emission intervals and light extinction intervals during a period from a time before said winder starts to wind said magnetic tape on said rotary head till said winder has finished winding is different from at least one of light emission intervals and light extinction intervals when said tape runs or travels after said magnetic tape is wound on the rotary drum.
- 5. A magnetic recording and reproducing apparatus for use with a magnetic tape having a light transmittable area on an end of said magnetic tape, comprising:
- a light emitter emitting a light through said magnetic tape;
- a light receiver sensing a light emission of said light emitter means to recognize a tape end when a tape taken-up position is said tape end;
- a light controller controlling light emission/extinction of said light emitter;
- a rotary drum having a magnetic head mounted thereon:
- a winder for winding said magnetic tape onto said rotary drum;
- a tape driver for traveling said magnetic tape;
- a tape take-up for taking-up said magnetic tape;
- a tape supplier for supplying said magnetic tape;
- wherein at least one of light emission intervals and light extinction intervals of said light emitter when at least one of said tape take-up and said tape supplier is deviated from an associated one of respective predetermined revolution speeds which vary in accordance with current tape taken-up position, are different from at least one of light emission intervals and light extinction intervals of said light emitter when both said tape take-up means and tape supplier means are at [predetermined revolution speeds] the respective predetermined revolution speeds at current tape taken-up position.
- 6. A magnetic recording and reproducing apparatus for use with a magnetic tape having a light transmittable area on an end of said tape, comprising:
- light emitting means for emitting a light to illuminate said magnetic tape;
- light receiving means for sensing a light emission from said light emitting means to recognize a tape end when a taken-up position of said tape is the end of said tape;
- means for controlling light emission/extinction of said light emitting means;
- a rotary drum having a magnetic head mounted thereon;
- means for winding said magnetic tape onto said rotary drum;
- means for traveling said magnetic tape by pinching said magnetic tape by pinching said magnetic tape with a driving axis and a rotatable member, wherein at least one of said driving axis and rotatable member has a movable mechanism to switch between pinching and non-pinching of said magnetic tape and at least one of light emission intervals and light extinction intervals of said light emitting means during a period from a tape non-pinching state till the tape reaches a predetermined traveling speed after the tape is pinched through said movable member are different from at least one of light emission intervals and light extinction intervals of said light emitting means when said magnetic tape is traveling at said predetermined speed by said means for traveling.
