    摘要： A system and method which is used to identify and discriminate the type of data storage cartridge that has been inserted into a disk drive. A system for identifying a type of data storage cartridge having a marker comprises a light source for emitting light to illuminate the marker, a first photodetector for measuring a first intensity of light received from the marker, a second photodetector for measuring a second intensity of light received from the marker; and a microprocessor for determining the type of data storage cartridge responsive to said first intensity and said second intensity. The determination is made responsive to a comparison of the first and second intensities. An optical detection mechanism is provided so that it can be ascertained with near certainty that an inserted object is an appropriate disk cartridge of a certain type or generation. Sensor comparison (e.g., subtraction or division) is used to distinguish between objects that return light directionally to its source and objects that return light diffusely.

    摘要： A data storage disk having a latent illuminance discrimination marker for determining whether the data storage disk is suitable for use in a disk drive. A light source illuminates the marker and the marker emits illuminance, preferably as phosphorescence. A detector detects the emitted illuminance, and a predetermined characteristic of the marker in the frequency domain is determined. The frequency domain response may be either a phase response or an amplitude response, or both. The frequency domain response provides identification of different types or generations of data storage disks or provides a secure keying mechanism for authorized access to proprietary software.

    摘要： An improved disk cartridge has a light emitter and a light detector and a baffle plate disposed between the emitter and the detector. The detector functions to denote the presence of reflected light from a retroreflective marker disposed on a disk cartridge. The baffle plate acts as a filter to minimize the amount of light reflected from sources other than the retroreflective marker that is received by the detector. By minimizing the amount of light seen by the detector from sources other than the retroreflective marker, the retroreflective marker on a disk cartridge can be placed in close proximity to the emitter and detector. It is advantageous for a disk drive of compact design, such as those within a lap top computer.

    摘要： A head loading mechanism for a removable cartridge disk drive comprises a support base fixedly mounted in the drive, and a moveable member movably attached to the support base via a pair of elongate flexures. The moveable member has a ramped surface adapted to engage a suspension arm at the distal end of an actuator. A read/write head is mounted on the suspension arm. The moveable member moves upon the flexures in tandem with the actuator as it moves toward and away from the edge of a disk inserted in the drive. The moveable member carries the suspension arm of the actuator to the edge of the disk, at which point the suspension arm can ride up and down the ramped surface of the moveable member in order to load the read/write head onto the surface of the disk and then subsequently to unload the read/write head from the disk.

    摘要： A storage media is disclosed and comprises a storage body and a readable indelible mark formed in the body such that portions thereof are indelibly altered. The mark is read by writing first data to the body in the region of the mark, and reading second data from the body in such region. The written first data is not accepted where the portions of the body are indelibly altered. Accordingly, the read second data corresponds to the written first data with segments thereof missing. The missing segments of the first data correspond to the portions of the body indelibly altered. In a preferred embodiment, the storage media comprises a magnetic rotatable disk having a substantially planar substrate and a magnetizable layer deposited thereon. The reading and writing are therefore performed magnetically.

    摘要： A disk cartridge comprising a rotatable disk having upper and lower surfaces; an outer casing for rotatably housing the disk, the casing comprising upper and lower shells that mate to form the casing, each of the upper and lower shells having an inner surface disposed in facing relation to a respective surface of the disk; and a spun fabric liner comprising a plurality of PTFE fibers, the fabric liner being attached to the inner surface of one of the upper and lower shells, a main body of the fabric liner lying against the inner surface of the one shell and being spaced a predetermined distance from the respective surface of the disk, whereby the fibers wipe the surface of the disk while the main body of the liner remains spaced from the disk, thereby reducing drag on the disk.
