Abstract
A data storage apparatus (HDD unit) having a cartridge, attachable to and detachable from a personal computer, incorporating a recording disk, comprises a switch circuit for inhibiting data reading and writing with respect to a magnetic disk and a locking mechanism for detecting that the cartridge is detached from the personal computer and causing data reading and writing inhibiting means to operate in response to the detection.
Claims15
A portable data storage apparatus, comprising:
- a hard disk drive which is attachable to and detachable from information equipment and incorporates a data recording medium or recording element;
- an impact sensor, incorporated in the hard disk drive, for detecting an impact applied to the hard disk drive;
- and
- an impact information providing device configured for providing impact information indicating that the data storage apparatus has received a great impact, when the impact detected by the impact sensor is greater than a preset value,
- wherein the impact information providing device includes a display configured for displaying the impact information.
A portable data storage apparatus, comprising:
- a hard disk drive which is attachable to and detachable from information equipment and incorporates a data recording medium or recording element;
- an impact sensor, incorporated in the hard disk drive, for detecting an impact applied to the hard disk drive;
- and
- an impact information providing device configured for providing impact information indicating that the data storage apparatus has received a great impact, when the impact detected by the impact sensor is greater than a preset value,
- wherein the impact sensor comprises a substrate, at least one flexible beam connected to the substrate, at least one inertia part supported by the flexible beam, a signal wire insulatively disposed over the substrate and extending from the substrate to the inertial part via the flexible beam, whereby when an impact greater than a predetermined impact value is applied to the sensor, the wire is broken together with the beam to detect the impact.
