A ramp-launched read/write device (50) for a data carrier comprising: an arm (54), a loading spring (55) having one end fixedly connected to the said arm (54) and a free end part (66), a platform (57) incorporating at least one read/write transducer, a carrier means (56) for carrying the platform, said carrier means comprising a suspension spring (56) having one end (56a) fixedly connected to the said arm (54) and a free end (63) for locating and supporting the platform (57), spring means (60, 65, 67, 69) for controlling the position of the platform (57) in relation to the data carrier (51), said controlling means (60, 65, 67) comprising a guide member having a level surface (61a) and at least one ramp surface (61b), and means (62) adapted to cooperate with the said guide member (61) for moving the platfrom (57) between a first, rest position and a second, read/write position close to the data carrier (51) to allow the data carrier (51) to be read from or written on, said controlling means (60, 65, 67) having said guide member (61) fixedly but flexibly connected to the said arm (54), the said free end part (66) of the loading spring contacting the said guide member (61) in accordance with the said positions of the platform (50) and anti-vibration means comprising a spring (69) having one end (61a) fixedly connected to the said arm (54) and a free end (60b, 69c) resting against the free end (63) of the suspension spring (56) of said carrier means for minimizing vibration of said platfrom.
Claim 3
Dependent Claim
39 words
A read/write device according to claim 1 wherein the free end of said suspension spring includes two arms (56b, 56c) interconnected to enable the platform to move between the said first and second positions while remaining parallel to itself.
Claim 4
Dependent Claim
57 words
A read/write device according to claim 2, including a frame (63) connected between said two arms (56b, 56c) and enclosing the platform, said arms being substantially parallel, said frame being carried by the two substantially parallel arms, said arms having their ends connected to the center parts of respective ones of two opposed sides of the frame.
Claim 5
Dependent Claim
22 words
A read/write device according to claim 3, wherein the parallel arms bend through approximately 180° and are substantially U-shaped at their ends.
Claim 6
Dependent Claim
38 words
A read/write device according to claim 1 wherein the carrier means (56) includes a tongue (56d) for supporting an intermediate connection between the platform (57) and a cable (59) adapted to be connected for tranlating a data signal.
Claim 7
Dependent Claim
48 words
A read/write device according to claim 1 wherein said loading spring includes prong means (66) extending from its free end part and being disposed adjacent said level surface (61a) such that the free end of the loading spring (55) is arranged to make contact with said level surface.
Claim 8
Dependent Claim
41 words
A read/write device according to claims 2, 3 or 6, wherein the carrier means (56) includes a tongue (56d) for supporting an intermediate connection between the platform (57) and a cable (59) adapted to be connected for translating the data signal.
Claim 9
Dependent Claim
51 words
A read/write device according to claim 2, 3 or 5, wherein said loading spring includes prong means (66) extending from its free end and being disposed adjacent said level surface (61a) such that the free end of the loading spring (55) is arranged to make contact with the level surface (61a).
