Abstract
In a disc cartridge and a disc drive apparatus, a disc cartridge has an identification opening where an identification plate is installed to be capable of sliding. A probing portion is installed at the disc drive apparatus and is turned on or off by interference with the identification opening. Thus, the type of a disc can be identified by the on/off actions, that is, by interference with the identification plate and probing portion.
Claims58
A disc cartridge having a disc where information is recorded and/or reproduced using a disc drive with a probing portion, comprising
- a case to rotatably accommodate the disc;
- and
- an identification unit disposed on said case to identify a type of the disc using the probing portion of the disc drive,
- wherein the probing portion selectively contacts said identification unit to produce a predetermined sequence of information to determine the type of the disc.
A disc drive apparatus to drive a disc rotatably accommodated in a disc cartridge having identification plates, comprising:
- a recording/reproduction unit to record and/or reproduce information with respect to the disc rotatably accommodated in the disc cartridge;
- and
- a probing portion to selectively detect the identification plates provided at the disc cartridge to produce a sequence of information to identify a type of the disc.
A disc identification mechanism to identify a type of a disc in a disc cartridge using a disc drive to record and/reproduce information on the disc and having a probing portion, the mechanism comprising:
- identification openings installed at the disc cartridge, each said identification opening having an identification plate slideably attached therein;
- and
- a probing portion installed at the disc drive to identify the type of the disc by detecting positions of the identification plates,
- wherein a contact between said probing portion and the identification plates produces a sequence of information to identify the type of the disc.
A disc cartridge having an information recording medium and which is received by an apparatus having a probing portion, comprising:
- a case to accommodate the information recording medium;
- and
- identification units disposed on said case to be sequentially detected by the probing portion of the apparatus to produce a predetermined sequence of information to determine a type of the information recording medium.
18 The disc cartridge of claim 17, wherein the sequence of the information is produced by a relative motion between said identification units and the probing portion.
The disc cartridge of claim 18, wherein:
- each of said identification units comprises an identification opening having an identification plate disposed therein, and
- a position of the identification plate is detected by the probing portion to indicate a feature used to identify the type of the information recording medium.
The disc cartridge of claim 18, wherein:
- said case further comprises a top side disposed above or below a recording surface of the information recording medium, and
- said identification units are disposed on the top side.
The disc cartridge of claim 18, wherein:
- said case further comprises a top side disposed above or below a recording surface of the information recording medium, and a second side disposed adjacent the top side, and
- said identification units are disposed on the second side.
A disc drive apparatus to record and/or reproduce data with respect to an information recording medium disposed in a disc cartridge having identification units, the apparatus comprising:
- a turntable to receive the information recording medium;
- a motor to drive said turntable to turn the information recording medium;
- an optical pickup to record and/or reproduce data with respect to the information recording medium;
- a controller to control said motor and said optical pickup according to a type of the information recording medium;
- and
- a probing portion to sequentially detect the identification units of the disc cartridge, and to provide the detected information to said controller,
- wherein said controller determines the type of the information recording medium according to the detected information.
40 The disc drive apparatus of claim 31, wherein said probing portion comprises a probing sensor and a probing tip, where the probing tip detects states of each of the identification units and the probing sensor provides the detected states to said controller as the detected information.
The disc drive apparatus of claim 40, wherein:
- the probing sensor detects a first state if the probing tip contacts an identification plate of the identification unit, and
- the probing sensor detects a second state if the probing tip detects an identification opening of the identification unit and does not contact the identification plate of the identification unit.
A method of detecting a type of an information recording medium disposed within a disc cartridge using a probing portion of an apparatus, comprising:
- passing a first identification unit of the disc cartridge by the probing portion and detecting a first feature of the information recording medium from the first identification unit using the probing portion;
- passing a second identification unit of the disc cartridge by the probing portion and detecting a second feature of the information recording medium from the second identification unit using the probing portion;
- and
- determining a type of the information recording medium based upon the detected first and second features.
A computer readable medium encoded with processing instructions for implementing a method of detecting a type of information recording medium disposed in a disc cartridge performed by a computer, the method comprising:
- receiving a first information signal in response to a first identification unit of the disc cartridge passing by a probing portion of an apparatus and detecting a first feature of the information recording medium from the first identification unit using the probing portion;
- receiving a second information signal in response to a second identification unit of the disc cartridge passing by the probing portion and detecting a second feature of the information recording medium from the second identification unit using the probing portion;
- and
- determining a type of the information recording medium based upon the detected first and second features.
An apparatus to identify a type of information recording medium, comprising:
- a probing portion;
- a case to accommodate the information recording medium;
- identification units disposed on said case to be sequentially detected by said probing portion to produce a predetermined sequence of information;
- and
- a detection unit to determine the type of the information recording medium using the predetermined sequence of information.
57 The apparatus of claim 50, wherein said probing portion comprises a probing sensor and a probing tip, where the probing tip detects states of each of said identification units and the probing sensor provides the detected states to said detection unit.
The disc drive apparatus of claim 57, wherein:
- the probing sensor detects a first state if the probing tip contacts an identification plate of said identification unit, and
- the probing sensor detects a second state if the probing tip detects an identification opening of said identification unit and does not contact the identification plate of said identification unit.
