Data system
A data system ( 1 ) includes a credit card type substrate ( 3 ) and a data unit ( 2 ). The substrate has first and second edges ( 28, 30 ) and a data surface region ( 26 ) between the edges. The data unit includes a base ( 4 ), a substrate support ( 60 ) mounted to the base for controlled movement along a first path ( 14 ), and a data head driver ( 6 ), also mounted to the base, including a data head which reciprocates along a second path ( 10 ) oriented perpendicular to the first path. The data head contacts the data surface region on the substrate and first and second data head support surfaces ( 120, 122 ) located at opposite ends of the second path adjacent to the first and second edges of the substrate. The data head support surfaces and the data surface rer˜ioI 1 are coplanar. The data unit also includes a substrate feeder ( 16 ), which delivers the substrate to and removes the substrate from the substrate support, and a substrate positioner ( 68, 70, 82, 94, 98 ), which properly positions the substrate on and secures the substrate to the substrate support.
1. A data system comprising:
an elongated magnetic data storage medium extending along an axis;
a housing comprising a panel;
an opening formed in the panel sized for passage of the magnetic data storage medium therethrough along a first path substantially parallel to the axis;
a support for receiving said magnetic data storage medium and which is movable between a load/unload position and a read/write position wherein the load/unload positioned is along said first path and said read/write position is located on a second path substantially perpendicular to said first path;
a handler mechanism comprising at least one pair of driving members for engaging and moving the magnetic data storage medium between the opening and the support;
a data head; and
means for moving at least one of the data head and the support carrying the magnetic data storage medium relative to one another such that the data head is operably positioned to read data from and/or write data to the magnetic data storage medium when the support is at the read/write position.
2. The data system according to claim 1 wherein the moving means includes means for moving the data head along substantially parallel tracks relative to the magnetic data storage medium.
3. The data system according to claim 1 wherein the substantially parallel tracks are constant-radius curved tracks.
4. A data unit, for use with an elongated magnetic data storage medium having first and second edges and a data surface region therebetween, comprising:
a base;
a support, configured to support said elongated magnetic data storage medium, mounted to the base;
a data head drive mounted to the base, the data head drive comprising a data head reciprocally moveable along a second path;
a step driver controllably moving at least one of the data head drive and the support relative to one another along a first path and said second path;
first and second data head support surfaces positioned at opposite ends of a second path and adjacent to said support, said first and second paths being transverse to one another; and
said data head comprising a data head surface which contacts said first and second data head support surfaces as said data head moves along the opposite ends of said second path.
5. A method for reading and/or writing data from/to a plurality of parallel data tracks on a magnetic data storage medium, the method comprising:
moving said magnetic data storage medium on a support to a location accessible by a data head;
positioning a data head at a first position relative to the magnetic data storage medium;
moving the data head along a first data track of the magnetic data storage medium in a manner that facilitates reading and/or writing of data from/to the first data track;
repositioning the data head to a second position relative to the magnetic data storage medium by moving the data head in a direction substantially perpendicular to the first data track;
moving the data head along a second data track of the magnetic data storage medium in a manner that facilitates reading and/or writing of data from/to the second data track, wherein the first and second data tracks are parallel data tracks.
6. The method according to claim 5 , wherein the first and second data tracks are substantially straight data tracks, and wherein moving the data head comprises moving the data head along the first and second data tracks.
7. The method according to claim 6 , further comprising continuing to move the data head along extensions of the first and second data tracks, said extensions passing adjacent to data head support surfaces.
