摘要： A disk drive includes a spindle motor (SPM) with a sensor. When the SPM with the sensor is set, an SPM driver outputs a low signal (L) to control unit. When a sensorless SPM is set, another SPM driver outputs a high signal (H) to the control unit. In response to the low signal, the control unit is switched to control the rotation of the SPM with the sensor. In response to the high signal, the control unit is switched to control the rotation of the sensorless SPM.

摘要： The present invention is a semiconductor device that includes a DRAM and an internal mask ROM that are implemented on a single integrated circuit substrate. The semiconductor further includes a terminal coupled to an external ROM and a selector for choosing an external ROM or an internal mask ROM for program code loading. If an external ROM is coupled to the aforementioned terminal, the external ROM is given precedence for use in the loading of the aforementioned program code. The control method of the present invention pertains to a semiconductor device including a DRAM, an internal mask ROM, a terminal coupled to an external ROM, a selector for choosing the first path led from the internal mask ROM or the second path led from the terminal, and a coupling determiner deciding whether or not the terminal is coupled to the external ROM. The control method includes the steps of: (a) deciding whether or not the terminal is coupled to the external ROM; (b) selecting a first path when a terminal is not coupled to the external ROM or a second path when the terminal is coupled to the external ROM; and (c) loading a program code from either the internal mask ROM or the external ROM.

摘要： A tape cassette of this invention is equipped with a memory capable of accommodating management information. Where the tape cassette is used, a MIC mode switch is written to a predetermined area on the magnetic tape held in the cassette. That item of information specifies whether or not the use of the management information held in the memory is mandatory upon write or read operation to or from the magnetic tape. A check is made on the consistency between the MIC mode switch read from the magnetic tape on the one hand and a result of access to the memory on the other hand. If an inconsistency is detected, that is interpreted as something fraudulent having been committed on the tape cassette. In such a case, read and write operations on the illegitimate cassette are restricted. This improves security of a tape drive system running the tape cassette.
