Magnetic recording and/or reproducing device with tape engagement means which moves in a concentric path with the head

Claim 2

A recording and/or reproducing apparatus comprising magnetic tape on spaced takeup and supply reels, a cylindrical tape guide drum, at least one rotary head moving in a path substantially coinciding with the periphery of said drum, at least one engaging means adapted to engage said tape when said apparatus is in an inactive condition, means for moving said engaging means in an arcuate path about at least a portion of the periphery of said drum during which movement said tape is moved into engagement with said drum for scanning by said rotary head, additional tape engaging means for holding the tape away from said guide drum except at said predetermined portion thereof, and said means for moving said engaging means also moving said additional tape engaging means whereby said additional tape engaging means and said engaging means move in synchronism.

Claim 3

A magnetic recording and/or reproducing apparatus comprising magnetic tape on spaced takeup and supply reels, a cylindrical tape guide drum, at least one rotary head moving in a path substantially coinciding with the periphery of said drum, at least one engaging means adapted to engage said magnetic tape when said apparatus is in an inactive condition, means for moving said engaging means in an arcuate path about at least a portion of the periphery of said drum during which movement said magnetic tape is moved into engagement with a predetermined peripheral portion of said drum for scanning by said rotary head, and the arcuate path of said engaging means being substantially concentric with the path of travel of said head.

Claim 4

A magnetic recording and/or reproducing apparatus comprising magnetic tape on spaced takeup and supply reels, a cylindrical tape guide drum, at least one rotary head moving in a path substantially coinciding with the periphery of said drum, at least one engaging means adapted to engage said magnetic tape when said apparatus is in an inactive condition, means for moving said engaging means in an arcuate path about at least a portion of the periphery of said drum during which movement said magnetic tape is moved into engagement with a predetermined peripheral portion of said drum for scanning by said rotary head, and the arcuate path of said engaging means being substantially concentric with the path of travel of said head.

Claim 5

Apparatus in accordance with claim 2 wherein the diameter of the path of travel of said engaging means is greater than the diameter of the path of travel of said head.

Claim 6

Apparatus for recording and/or reproducing on magnetic tape, said apparatus comprising a cylindrical drum, support means for said drum, at least one rotary head moving in a head path substantially coinciding with the periphery of said drum and lying in a plane perpendicular to the axis of said drum, means for supportiNg supply and takeup reels for the magnetic tape with the tape path between the reels and said plane of the head path being inclined relative to each other, at least one engaging means adapted to engage said tape between the reels when said apparatus is in an inactive condition, means for changing said engaging means to an active condition by moving said engaging means in an arcuate path about at least a portion of the periphery of said drum to bring said tape into helical engagement with said drum for scanning of said tape by said rotary head, and additional tape engaging means for holding the tape away from said guide drum except at said predetermined peripheral portion thereof.

Claim 7

Apparatus for recording and/or reproducing on magnetic tape, said apparatus comprising a cylindrical drum, support means for said drum, at least one rotary head moving in a head path substantially coinciding with the periphery of said drum and lying in a plane perpendicular to the axis of said drum, means for supportiNg supply and takeup reels for the magnetic tape with the tape path between the reels and said plane of the head path being inclined relative to each other, at least one engaging means adapted to engage said tape between the reels when said apparatus is in an inactive condition, means for changing said engaging means to an active condition by moving said engaging means in an arcuate path about at least a portion of the periphery of said drum to bring said tape into helical engagement with said drum for scanning of said tape by said rotary head, and additional tape engaging means for holding the tape away from said guide drum except at said predetermined peripheral portion thereof.

Claim 8

The apparatus of claim 4, further comprising a cassette housing said reels and having an opening at which a run of said tape between said reels is exposed, and in which said engaging means includes a pin which, in said inoperative condition of the apparatus, extends into said opening of the cassette and lies at the side of said tape run facing away from said guide drum.

Claim 9

The apparatus of claim 4 in which said supply and takeup reels are spaced different distances from the end of said drum closer to said support means, and at least said additional tape engaging means pass between said tape and said support means as said one engaging means and said additional means move from said inactive position to said active position.

Claim 10

The apparatus of claim 4, in which said takeup and supply reels are axially superposed.

Claim 11

The apparatus of claim 4, further comprising fixed magnetic heads disposed to be engaged by said tape between said guide drum and said reels when said tape is moved into engagement with the drum.

Claim 12

The apparatus of claim 4, wherein said additional tape engaging means are connected with said one engaging means for movement with the latter.

Claim 13

The apparatus of claim 9, in which said one engaging means is in the form of a guide pin and said additional tape engaging means is in the form of an arcuate plate extending from said guide pin.
