An apparatus and method for retrieving data related to a data cartridge contained in a media storage system. A transponder (e.g., an RFID transponder) is attached to the data cartridge for storing the related data and a reader attached to a cartridge access device of the media storage system is positionable adjacent the data cartridge for reading the related data from the transponder. The reader is attached to a cartridge plunge mechanism so that the reader is positioned near the transponder regardless of the mechanical tolerances of the media storage system. Once positioned adjacent one another, the transponder is activated and queried by the reader. The transponder transmits a data signal containing the related data to the reader and a controller operatively associated with the reader processes the data signal.

In conjunction with a so-called patterned medium comprising recording tracks each having an array of unit minute recording portions of a magnetic material separated by non-recording portions of a nonmagnetic material, the invention aims to prevent a magnetic head slider from sticking to the medium. The magnetic recording medium of the invention includes recording tracks each having an array of unit minute recording portions (14) of a magnetic material separated by non-recording portions (16) of a nonmagnetic material. The surface height of the unit minute recording portions (14) is set higher than the surface height of the non-recording portions (16).

The reflectance of an optical recording medium for which high speed recording using a laser beam with blue wavelength or a shorter wavelength than blue light is possible is adjusted to a predetermined value of no more than 60%. A recording layer 18 of a high-speed write-once type optical recording medium 10 is formed by laminating first and second sub-recording layers 18A, 18B, each of which contains one type of different metal as a primary component. When laser beam of a blue wavelength is irradiated onto the recording layer 18, the irradiation causes the primary component metals contained within each of the first and second sub-recording layers 18A, 18B to diffuse and mix, and this mixing forms a recording mark with an irreversibly changed reflectance. The recording layer 18 is sandwiched between first and second dielectric layers 20, 16, and by adjusting the material and the thickness of the recording layer 18 and the first and second dielectric layers 20, 16, the reflectance of the unrecorded sections can be adjusted to a value within a range from 5% to 60%.

An improved optical disc is provided that comprises a substantially transparent substrate, one surface of which carries optical data structures comprising pits and lands radially outward of a clamp area of the disc. In the clamp area a protrusion structure is provided above the first surface to create a clamp thickness greater than the thickness of the rest of the disc. In accordance with the principles of the present invention, only a portion of the clamp area is covered by the protrusions, which emulate a disc having a clamp area of greater thickness. In order to reduce warping caused by shrinkage of material added to the clamp area, the amount of material used to form the protrusions is less than 5% of the amount of material used to form the rest of the clamp area.
