A disk drive includes a disk rotating unit, a traverse base holding the disk rotating unit, a damper member holding the traverse base, a main unit holding the traverse base through the damper member, a tray mounting a cartridge housing the disk, a driving unit that loads or ejects the tray and moves the disk in the cartridge relative to the disk rotating unit, and a traverse base holding member that is moved vertically by the driving unit relative to the main unit at the time of tray loading or tray ejection. The traverse base is held by the traverse base holding member through the damper member, and the resonance frequencies of the damper member in the radius direction of the disk as it is being loaded and in the direction of a rotation shaft are set higher than the maximum rotational frequency of the disk.

Disk drive with established resonance frequencies for damper member

A disk drive includes a cartridge holding mechanism which has a small size and reduces a damper load. The disk drive includes a spindle motor which mounts and rotates a disk. A traverse base holds the spindle motor, and a rubber damper flexibly holds the traverse base. A mechanical chassis holds the traverse base through the rubber damper, and a tray mounts a cartridge in which a disk is housed. A loading motor moves the disk in the cartridge close to the spindle motor or away from the spindle motor. The cartridge is supported by the mechanical chassis through the tray.

Disk loading apparatus with cartridge urging member operating cooperatively with disk rotating unit transverse holder

An information recording/reproducing apparatus wherein the CPU stores data transferred through an interface in a temporary storage area and later records the data in a recording medium by using a recording/reproducing means. The temporary storage area is divided into first and a second regions by a temporary storage region disposition device. A discriminator determines whether the process-requested region is an information managing region or a data region from the process requests made by the host computer and the temporary storage region managing information. Based on the result of this discrimination, the temporary storage region manager allocates the first region if the data is for information managing or the second region if the data is intended for data storage.

Information apparatus with cache memory for data and data management

An information recording, reproducing apparatus comprising a first operation switch, a memory for storing a plurality of operation modes with operation steps for controlling the information recording, reproducing operation with the instructions from the control apparatus, a selecting apparatus for selecting a selecting mode, and a switching apparatus for selecting one operation mode from among the plurality of operation modes, where selection of an operation mode among from the plurality of operation modes is performed after a selection mode has been selected.

Information recording, reproducing apparatus having operation mode

An information recording reproducing apparatus is operable with a large-capacity recording medium and is operatively connected to a host computer. The apparatus has a cache memory for temporarily storing therein information transmitted from the host computer, and also has a write-back function and a write-through function. When recording using a write-back function designated by a recording designation flag, the maximum number of substitutions of defective sectors is automatically set to a given value for a write-back operation, and a mode display indicates that a write-back mode has been selected. The write-back operation is inhibited by a write-back inhibit flag according to the frequency of occurrence of the substitutions or the condition of a substitute area to thereby enhance the reliability of recording information.

Data information recording/reproducing apparatus which minimizes record

The present invention intends to record the information which was divisionally recorded on a disk onto a recording medium without a loss of information. The operation of a disk reproducing apparatus for reproducing the information recorded on the disk and the operation of a recording apparatus for recording the information reproduced by the disk reproducing apparatus are synchronously started. When the recording medium of the recording apparatus has reached an end, the reproducing operation of the disk reproducing apparatus is immediately stopped. The header signal of the music divisionally recorded on the disk is searched for by a searching means of the disk reproducing apparatus. The reproducing operation is temporarily stopped. After the recording medium is reversed, the reproduction of the disk reproducing apparatus is restarted from the searched for header signal.
